What goyim clean with paste. GOI paste for polishing: what it is, how to use it. What can not be polished

GOI paste, developed back in the distant 1930s in the bowels of the State Optical Institute, has not lost its former popularity even now. You can hardly find an owner who does not have a piece of this green (and sometimes other colors) hidden somewhere. Recall how to use GOI paste, and give some tips on the safe use of this "greetings from the past."

To date, there are four types of GOI paste on the market:

• No. 4 is used for the initial processing of the material, if it has not been processed before;
• No. 3 gives the surface a matte look, eliminates all remaining strokes;
• No. 2 and No. 1 complete what their "big brothers" started, make the surface glossy and complete the polish.

The type of GOI paste depends on the size of the abrasive used in its manufacture. Pasta was produced in a hard (bar) or softer (box) version. Why are we talking about GOI paste in the past tense? The fact is that at the moment not a single plant in Russia has the right to produce this product due to the presence of chromium oxide hazardous to health in its composition - this compound is a carcinogen, i.e., it accelerates the development of cancer cells.

Preparing for polishing

The action of GOI paste is the work of small abrasive particles, which, when rubbed, erase irregularities from the surface. Before you start polishing, you need to prepare a small piece of soft cloth and soak it in gasoline (it is not necessary to use automotive fuel, gasoline for lighters will be enough). A small amount of paste is applied to the matter. With the prepared tool, first wipe the unnecessary metal surface in order to eliminate excessively large abrasive particles, otherwise the desired surface will not be polished, but damaged. After all, you don’t want to see a scratch on the surface after polishing, right?

Polishing

After preparing the polishing tool, you can begin the process. To properly polish the surface, you need to gently, without sudden movements and strong pressure, rub the desired area with a polish until the surface becomes smooth. If necessary, you should return to the previous stage (if the surface requiring polishing has a large area, the GOI paste will quickly run out).

If the product has many flaws, you should use not one type of paste, but several. So, for primary processing, GOI No. 4 paste is applied to the rag, as the number of flaws decreases - No. 3, and so on, until the surface takes the desired form.

The treated element should be washed with kerosene in order to remove abrasive residues from it. In the absence of kerosene, ordinary running water can also be used, but this is not recommended, as there is a high risk of rust under improper conditions. Given the fact that many polish the necessary surfaces in the garage, where there is often high humidity, this moment should not be discounted.

Carry out polishing work outdoors. The ideal place would be a garage, a well-ventilated workshop, or some kind of open space. Polishing with GOI paste after itself requires washing with kerosene, and inhaling its vapors is dangerous to health.

Polishing of soft metal products

GOI paste can be used to polish products made of any metals, including soft ones such as silver and gold. This procedure will help restore the former shine of your favorite utensils. But polishing such objects requires a special approach.

Consider the polishing process on the example of silver spoons.

1. Before carrying out the procedure, you should thoroughly wash the spoons and clean them with a stiff brush (the most ordinary toothbrush is ideal) with tooth powder applied to it.
2. Then a solution is prepared containing ammonia, tooth powder and soap shavings. All this is mixed until completely dissolved.
3. Spoons are soaked in the resulting solution.
4. Then the mixture should be put on fire and brought to a boil.
5. Spoons are removed, washed in running water and after that they are wiped with GOI paste.

It will be better to use types #1 or #2, as the other two can leave scratches on expensive utensils.

Polishing plastic and glass products

It is amazing, but true: GOI paste can be used to restore the former beauty of aged technology! For polishing plastic products, GOI type No. 2 paste should be used, since more abrasive types can damage soft plastic.

It should be noted that kerosene, gasoline and running water are not used when polishing equipment. Only the abrasive is applied to the rag, without the use of auxiliary agents. The process itself is no different from polishing other materials and objects.

Where can not apply GOI paste?

It would seem that GOI pasta - universal remedy. But no, there are surfaces that you should not touch with this polish due to the fact that such a procedure will either make no sense or be harmful.

First, mechanical watches should not be polished with GOI paste. Types No. 1 and No. 2 will only enhance the visibility of small scratches, emphasize them, and pastes No. 3 and No. 4 can simply erase upper layer metal, due to which the watch will lose its former gloss.

You should also not use this tool for polishing sapphire glasses on watches - there will simply be no effect, since sapphire glass is very durable.

Precautionary measures

At the beginning, we mentioned that GOI paste is currently not produced in Russia due to its toxicity. However, it is freely available in stores whose owners were able to supply the well-known polish. And if a person acquires this remedy, he should know some precautions in order to avoid tragedy.

• GOI paste should be used with extreme caution, avoiding getting its particles on the mucous membranes of the eyes and nose. If it was not possible to protect yourself from this, immediately rinse the affected surface with running water and call an ambulance.
• Use a respirator or at least a medical mask when working with polish, especially when polishing metals using a cloth soaked in gasoline. You should not expose your body to the risk of poisoning with vapors of chemically complex substances.
• Keep children away from polish storage areas.
• Work with gloves to protect the skin of your hands.

So, GOI paste is an effective but unsafe remedy. Even if you have used it for polishing many times, you should always be on the lookout when working. If the situation allows, it is better to use more gentle methods.

GOI paste is a universal cleaning product that can successfully grind and polish any surface: from rough metal to the screen of a tablet and phone. Polishing with GOI paste is simple and effective, so every owner should keep a treasured jar with a greenish mixture at hand.

Pasta GOI: what is the green mass?

The name stands for: State Optical Institute. This cleaning material was created there in the 30s. last century. It looks like a mass of a greenish tint, sold in the form of a smooth bar and in a sealed jar.

The composition of the cleaning agent

The main component in the composition is chromium oxide. The granularity of the preparation and characteristics directly depend on its concentration. The higher the percentage of chromium oxide, the coarser the composition (variation can be from 60 to 85%).

Important! The green mixture is harmless to humans due to the fact that 3-valent chromium oxide is used in its creation, and only 6-valent is harmful. Nevertheless, it is recommended to wear goggles and a mask during work, because when using it, dust appears that irritates the human mucosa.

Varieties of pasta differ in graininess. Each of them is given a special number:

• No. 4 - rough. In it: chromium oxide - 81%, stearin - 10, fat - 5, kerosene - 2, silica gel - 2. Light green shade, it is best to comb off the top layer of the material. Removes large scratches left by other abrasives.
• No. 3 - medium. Chromium oxide - 76 parts, fats - 10, stearin - 10, kerosene - 10, silica gel - 2. Pure green hue. Cleans small bumps and scratches, gives the material a dull finish.
• No. 2 - thin. Chromium oxide - 74 parts, stearin - 10, fat - 10, oleic acid - 2.8, kerosene - 2, silica gel - 1, baking soda - 0.2. This composition is characterized by a dark green color. Used for polishing most products.
• No. 1 - thin. Nitric oxide - 65-70%, stearin - 10, fat - 10, kerosene - 10, silica gel - 1.8, soda - 0.2. Differs in a dark color with an outflow of greenery. Goi pastes 1 and 2 are designed for lapping or finishing the material, and give it shine and shine.

Important! The most common is the composition of the paste GOI No. 2. It is ideal for products made of precious and non-ferrous metals, as well as glasses and plastics.

Dried green mixture can be "reanimated" to become soft again. This is done with engine oil. On a small piece, pounded into small crumbs, drop 3-4 drops of machine or any other technical oil. Place in the microwave for 30 seconds, and grind the ingredients into a homogeneous mass.

GOI paste for car

Over time, scratches appear on the body of the car, headlights and glass dim, which at times impairs the driver’s visibility. It would be logical from time to time to carry out polishing in a car dealership or with your own hands. A proven green mixture will help to cope with problems.

Sanding or polishing?

All car owners should understand the fundamental differences between these processes.

• Grinding is a rough method of exposure to abrasives, which, by combing the top layer, equalize the surface. Used for severe scratches. After it, the canvas will become dull, and additional exposure to compositions with fine grains will be required.
• Polishing is the final step after sanding. The goal is to give shine to the product using fine-grained products.

Interesting! To understand what kind of GOI paste is required for polishing or polishing the body, evaluate the condition of the car. To do this, run your fingernail over it. If it clings to a scratch, then the body will need grinding No. 3, and if not, then impact No. 2 or No. 1 will do.

Features of grinding different parts of the car

For polishing the windshield, headlights or mirrors, take flannel, and felt is suitable for the body. Polishing paste is applied as follows:

For windows and headlights:

• Initially wash the glass with water and shampoo, glass cleaner or alcohol, wipe dry. This will enhance the effect.
• Polishing glass or headlights from scratches should be done with a special machine with a grinding wheel or a drill with a felt nozzle. Manual work will only remove haze.

• Mix the green mass with machine oil at the rate of a drop of oil per spoonful of goy. Apply the mixture to the flannel wheel of the polisher. Carefully process the desired places or, if desired, all glass.
• The direction of movement can be any, but the principle of overlapping lanes is welcome.

• Periodically remove the remnants of GOI with a paper towel, and evaluate the result. Finish only when the area is perfectly smooth.

Important! If you are working on a specific area, then the surrounding area must be covered with plastic wrap so that you do not wash the entire car later.

• Excessively deep scratches should not be sanded, but filled with a special colorless compound.

Important! For glass use only thin mixture No. 1 or 2. Keep an eye on the temperature of the glass, otherwise it will overheat and crack during the cleaning process.

For the body:

• To remove haze from the body, clean the surface with a glass cleaner and wet with water.
• Apply the paste on the circle of the car, wait until it accelerates to a speed of 1100 rpm, and, without stopping, move around the square, keeping the angle between the circle of the car and the body 4-6 degrees.
• Remove the remnants of the drug with warm water under low pressure.

Cleaning products using GOI depending on the material

The use of polishing composition depends on the type of material.

General principles of cleaning with GOI paste

Polishing the surface at home is easy. It is only important to adhere to general advice, and not to spoil the processed canvas. The use of the tool is carried out in the following sequence:

• To avoid scratches on the surface, take a piece of rag and soak it with gasoline.
• It is necessary to spread a little green mixture on a rag, wipe it on an unnecessary object made of metal or glass. So excessively large crystals will disintegrate.
• Rub the desired area with light movements without pressure until the body shines. This processing will take only 3-4 minutes. It is only important not to scratch the treated area with large particles.
• After finishing the treatment, you need to walk over the polished object again with gasoline or immerse the entire product in kerosene.

Metal processing with GOI paste

Before using GOI paste, it is important to determine the type of metal. For example, silver cutlery (knives, spoons, forks) turn green over the years, and high-quality cleaning is required. In order not to accidentally spoil the expensive material with roughness and scratches, clean according to the following scheme with variety No. 3:

• Wash all necessary silver utensils under running water.
• Scrub with a soft toothbrush and detergent.
• Separately, pour a glass of water into the saucepan, pouring in a spoonful of ammonia, a pinch of laundry soap and a whisper of washing powder.
• Boil appliances in this composition.
• Rub a piece of felt with a bar of paste, and process the appliances. Then take a softer cloth and grind each spoon for a few minutes.

• Speaking of other metals, goyim is used with great success for knives, drills and other tools. Cleaning of metals is carried out according to the above scheme.

• To grind the clock, you must first get the clock mechanism.

• Gold is cleaned with flannel or a piece of leather coated with mixture No. 1. Try to act without pressure so as not to damage the soft precious metal.

Important! Remember that the polishing agent is always applied to the cloth or grinding wheel, and not to the product. This way you will prevent the appearance of ugly scratches.

Handling the screen of a phone or tablet

To polish the screen of a mobile phone or tablet, you need composition No. 2 and a flannel rag.

Cleansing involves the following steps:

1. Apply the green preparation to the flannel in a thin layer.
2. Rub it on an unwanted metal or glass surface first to remove abrasives.
3. Rub the display with light movements without pressure for 5 minutes, be careful when working with a fragile product.
4. Wipe off residue with a clean, dry cloth. The screen will be rubbed to shine.

Important! The tool for plastic is used in the same way as for glass.

For what materials is GOI paste not suitable?

Do not forget that polishing even with such a miracle drug causes irreparable damage to some materials. Not recommended for:

• gilding (risk of erasing the top layer);
• steel and nickel (except scissors and knives);
• sapphire glass from watches (the procedure is ineffective).

The modern chemical industry offers a wide range of specialized abrasive compounds for polishing and grinding any materials. However, all modern tools are united by a narrow specialization (by type of surface to be treated and by grain size), as well as by the serious cost of branded polishes. As a universal analogue that adequately copes with the finishing of metal, plastic or glass, one can name the long-known GOI paste.

Composition and properties of GOI paste

Abrasive paste produced by the State Optical Institute was developed in the 30s of the last century as a means for high-precision finishing of the surfaces of metal, ceramic and glass parts. The original composition of the paste contained chromium oxide powder, which provided a memorable dark green tint to the composition.

Currently, chromium oxide is banned for use, as it is a toxic compound. Therefore, modern GOI pastes are produced on the basis of aluminum oxide. and are red or white.

The red tinted paste provides intense polishing, while the white compound is designed to create a smooth glossy surface.

The paste also contains plasticizers and binders, such as stearin, silica gel and kerosene, and auxiliary additives.

Depending on the size of the abrasive fraction, GOI paste is divided into the following types:

• No. 4 is intended for primary processing (removable layer from 20 to 40 microns);
• No. 3 for the formation of a matte surface without scratches from abrasive particles;
• No. 2 and No. 1 for final fine polishing (removable layer no more than 0.1 microns).

According to the form of release, GOI paste comes in bars, tubes and containers, and there are also polishing wheels impregnated with the composition for grinders.

Car enthusiasts and service stations successfully use GOI paste for grinding and polishing car glass (especially windshield), mirrors, as well as headlights and other lighting fixtures.

headlights

Car lights - important element ensuring traffic safety. They must provide the intensity and dispersion of the light flux sufficient for confident movement at night and in conditions of poor visibility. The vast majority of traffic accidents at night occur due to insufficient lighting or malfunctioning lighting devices.

Most modern cars are equipped with plastic headlights, but there are headlights and fog lights with glass diffusers.

With prolonged use of the car, the glass of the headlights becomes cloudy under the influence of the external environment. Solid dust particles and small stones leave scratches and micro-chips on the outer surface of the headlights. Plastic headlights also often become cloudy from the ingress of tar, engine oil and aggressive auto chemicals. You can restore the transparency of the headlights using GOI paste. To assess damage to the outer surface of the headlights, they should be thoroughly cleaned of dirt and dust using specialized detergents. Particles of dirt not removed from the glass of the headlight will lead to the formation of additional scratches during subsequent grinding.

Polishing headlights with GOI paste is done manually or using a felt nozzle on a drill. To achieve the desired effect, it is necessary to treat the damaged surface for at least 3-4 minutes. Periodically, the headlight should be cleaned of dust and excess paste with a dry cotton cloth, and the result should be evaluated. Grinding is carried out until the headlight glass acquires absolute smoothness.

If the transparency of the headlight could not be restored by grinding from the outside, then the defect is on its inner surface. This problem is typical for plastic lighting fixtures: under the influence of high temperatures from halogen or xenon lamps, the inside of the headlight becomes cloudy. To restore transparency, it is necessary to disassemble the headlight and polish the inside of the lens. Glass headlights, as a rule, do not need to be polished from the inside, it is enough to wash the light-transmitting surface well with a glass cleaner.

In a similar way, using GOI paste, you can restore the appearance of burnt or worn taillights.

Attention! During manufacture, a protective coating is applied to the surface of plastic headlights, which is peeled off during the grinding process. Therefore, after polishing with GOI paste, it is necessary to re-coat the treated area with a special varnish in several layers. The protective film dries after at least 24 hours.

The sequence of actions when polishing the headlights with your own hands can be seen in the following video:

Glass

When the car is moving, grains of dust and debris carried by the oncoming air flow intensively damage the outer surface of the cabin glazing with sharp edges. Additional damage to the windshield in the form of chips and cracks is caused by small stones flying out from under the wheels of oncoming vehicles, as well as grains of sand that have fallen on the wiper blades. Door glasses with repeated activation of power windows are scratched by solid dust particles that have settled on the inside of the seals - velvet. Excessive efforts when cleaning the glass from adhering ice and snow with a hard scraper or wiping with a dry coarse cloth also add mechanical damage.

As a result, the glass becomes dull, cracks, scratches and abrasions impair visibility, and at night they distort the headlights of oncoming cars, blinding the driver.

Shallow damage to glass (up to 300 microns), microcracks, chips and local abrasions from wipers can be eliminated by grinding and polishing glass using GOI paste.

In the presence of deep scratches, extended cracks and chips, grinding can lead to loss of transparency and curvature of the glass surface. In this case, it is advisable to replace the glass with a new one.

Before polishing car windows with GOI paste, they must be thoroughly washed and dried. Defective zones are recommended to be marked with a marker on the inside of the glass. Adjacent parts of the roof, pillars and hood must be protected from accidental damage with masking tape or other material. Polishing (especially when using a power tool) should be done with care so as not to damage the glass.

To polish the windshield, use only GOI finishing paste with a minimum size of abrasive particles (No. 1).

How to breed

Before use, GOI polishing paste requires preliminary softening. Initially, the paste can be quite dry, making it difficult to apply to the polishing cloth, and hard clumps will cause unnecessary scratches on the glass during processing.

The list of liquids used to soften the material is quite extensive: from distilled water, industrial and motor oils to white spirit and refined gasoline for lighters.

It is not recommended to dissolve GOI paste with gasoline or white spirit. due to their flammability, besides, it is difficult to neutralize the specific pungent odor of these liquids later. A more practical way is:

• a small amount of engine oil should be applied to a bar of GOI solid paste with a syringe or pipette;
• the liquid is rubbed into the bar with a flannel or cotton cloth until the paste becomes like plasticine in consistency;
• the resulting plastic mass can polish defective areas of glass or headlights without the risk of damage.

For greater uniformity, a mixture of GOI paste with engine oil before use, you can warm up (for example, in the microwave) and mix thoroughly.

Advice! Prepare the polishing mixture in batches. Over time, the liquid evaporates and the paste becomes solid again.

The glass or plastic surface to be treated must also be moistened with water, lubricated with industrial or engine oil. If you apply GOI paste on dry glass, it is likely that the outer layer will become dull.

How to use

The principle of processing with GOI paste is that the small particles contained in the paste clean off a thin layer of glass simultaneously with microcracks and scratches.

The pre-prepared paste should be applied to a cloth or buffing pad and lightly rubbed on a hard surface to remove excess and particulate matter. After this, the defect sites are polished first with reciprocating movements with partial overlap of the strips, and then in a tapering spiral from the edge to the center of the damage.

Important! The paste should be applied only to the working surface of the tool, and not to the glass itself.

Periodically wipe the treated element with a damp cloth and control the condition of the polished surface.

Polishing with GOI paste using a grinder should be done at medium speed (no more than 1000 revolutions), with smooth movements without stopping the working tool in one place. The grinding wheel should be at an angle of no more than 5 degrees and have the maximum possible contact area with the workpiece. Should be constantly check the degree of heating of the polished surface(especially with plastic headlights) and, if necessary, stop grinding until the part has cooled.

Upon completion of polishing, the remaining paste and abrasive dust should be washed off with plenty of water, and then wipe the glass dry with a microfiber cloth.

To maintain the effect, it is recommended to repeat the polishing procedure approximately once every 1.5-2 years, depending on the operating conditions of the machine.

GOI paste can be used for polishing surfaces of products from a variety of materials. To date, several varieties of it are produced. For each specific material, a specific type of paste should be selected. In addition, the polishing procedure itself must be done correctly. We will talk about how to use GOI paste below.

History of pasta

Then pour a little ammonia into a glass of water, fine-tune the soap and pour in a little powder. All this must be thoroughly mixed until completely dissolved. Next, the liquid is poured into some kind of enameled saucepan. After that, silver cutlery is lowered into it. Then put the saucepan on the fire and bring the liquid to a boil. After that, the silver should be removed and washed in cold water. Then you can start processing it with GOI paste according to the method described above.

What can not be polished

Next, let's see in which cases GOI paste cannot be used. How to use it, you now know. However, in no case should this tool be used to process gilded things. Otherwise, the upper valuable layer will be very quickly erased to the lower metal. Steel (except knives) and nickel are usually processed not by hand, but using a special machine. Polishing of metal watches is also done with a cloth. However, they must first be disassembled and the mechanism pulled out. Do not start polishing too heavily scratched surfaces from option No. 2 or 1. In this case, the defects will become even more noticeable. Sapphire crystals on watches cannot be polished with GOI paste. She just won't take them.

Where is the tool used

We figured out how to polish with GOI paste. Now let's see where exactly this tool is used. GOI paste is used not only at home for polishing, silver, watches, dangerous blades and razors, etc., but also in production. In the latter case, it is most often used in the processing of products made of non-ferrous and ferrous metals. Polishing is done using special polishing machines with felt wheels.

Foreign analogues

Today, imported versions of such pastes can also be found on sale. A very popular option is the French Dialux. The latter has a harder consistency and is worse applied to the skin of the bar when sharpening knives than GOI paste. Dialux is considered more convenient to use. You can polish metal surfaces with it much faster and better. However, these pastes are more expensive. There are many more varieties of Dialux than types of GOI. This tool is produced in sticks, packed in paper of different colors. According to them, you can navigate in terms of using Dialux for a particular metal.

This paste is applied in much the same way as GOI, that is, with soft, smooth movements. However, its layer when polishing knives or other steel parts should be thinner. In this case, the paste will work in conjunction with the skin. As a result, the polishing efficiency will increase significantly.

Well, we hope that we have answered the question of how to use GOI paste correctly. The procedure for polishing with this tool is quite simple. Most importantly, wash your hands thoroughly after polishing.
