This post will discuss how to use GOI paste to polish objects in a practical way so that you can accomplish salon-caliber results at home. You can bring back the original beauty of your priceless items with a few easy steps.

History of the polishing agent

The paste was created in Russia during the 1930s of the 20th century. It was created by GOI staff members. The paste’s name, GOI, stands for the State Optical Institute, and is an acronym for that reason. Although this product was created over a century ago, it is still relevant today and is used to process:

• plastic;
• ceramics;
• stone;
• glass and metal.

The way our grandfathers used GOI paste was not new. When it was first made, it was made of green chromium oxide and other ingredients. These days, you can buy such a product in stores and on the market. However, the production of the green paste was outlawed. This is because chromium oxide is a carcinogen that is toxic.

The new GOI is available in red or white and is made of aluminum oxide. Polishing is much more intense when a red substance is used. But, you should use a white paste to create a coating that is exceptionally smooth and high-quality.

GOI paste is an adaptable polishing compound that can bring back the luster of a variety of materials, such as plastic, glass, and metal. It is a well-liked option for both professionals and do-it-yourselfers seeking to achieve a smooth, glossy finish on anything from jewelry to automobile parts because of its simple application and efficacy.

Types of green paste

There used to be four different kinds of green paste made. You can still find and purchase this product in the current abrasive market, with varying qualities based on the size of the abrasive particles:

• Sample No. 4 is capable of rough initial surface treatment;
• Abrasive marked No. 3 creates a matte look;
• Pastes No. 2 and 1 are used for final processing and add gloss.

Both solid bars and a more plastic-like ointment in boxes were produced for the green variety of GOI. The popularity of both varieties was accounted for by their very reasonable prices in addition to their superior processing quality.

Preparation for use

It is worthwhile to learn how to apply GOI paste to metal and other surfaces that need to be polished. When the coating is rubbed, the paste’s particles remove microscopic cracks and scratches from the surface. Typically, processing is done with a gentle cloth dipped in gasoline (a lighter can be used).

To clean the superfluous metal surface, dab the rag with a small amount of paste. The purpose of this action is to break up all of the big lumps. If any are left, the surface will appear rough and unpolished.

Actually, the rag ought to be soft. Take flannel, for instance. The product is sometimes used on a polishing wheel. On the actual product, polishing is not possible. Prior to use, the surface should be lightly coated with "Veretenka," a liquid industrial oil.

Instructions for various materials

The polishing tool is therefore ready. You can now move on to the actual processing. The product is just rubbed to accomplish this. Furthermore, applying pressure to the rag is not required in the slightest. In this instance, additional scuffs and anomalies might appear. You shouldn’t move your hand too sharply for the same reasons. You should continue to manipulate the rag until the surface is perfectly smooth. Periodically lubricate the product with "Veretenka" if needed.

Deep defects

When a product has severe scratches, paste option No. 4 is typically the first to be processed. Next, move on to No. 3. And polish No. 2 to perfection. No. 1 yields the ultimate shine. Kerosene, which you can purchase at a pharmacy, should be used to rinse the surface after finishing all operations.

If there was no kerosene available, the treated object may be rinsed under running water. In certain instances, zapon varnish is applied to the product following polishing, rinsing, and drying. which causes the oxidation process to be significantly slowed down.

Specifically, knives are processed using a leather belt or a piece of leather stretched over a wooden block.

Glass and plastic

The Government of India is frequently used to repair mobile phones. In this instance, the device’s body is polished before the display’s glass screen. Plastic is a fairly soft material, so you should use Jar No. 2 with fine grain to process the phone handset. If not, more severe scratches could be made to the body. The same techniques as for other materials are used to polish plastic.

Specially designed rubber circles are used as a pre-treatment for the glass screen. Next, the GOI product is put to use. Throughout the entire procedure, a rag is used. In this instance, there is no use of oil or gasoline treatment.

Silver items

Any kind of GOI composition—red, white, or green—can be used to polish any kind of metal. This holds true for silver jewelry as well as tableware. You can safely use GOI to clean silverware that has become discolored over time, among other things.

Use a toothbrush and tooth powder to give the silver item a thorough cleaning right before polishing. Next, dissolve soap shavings in a glass of water, dilute the washing powder, and add a small amount of ammonia. After that, stir the mixture until every ingredient has dissolved. Next, gradually transfer the contents of the glass into a bowl made of enamel.

After that, place the silver cutlery there, light it, and bring it to a boil. It is then necessary to remove the items, rinse with cold water to remove any leftover mixture, and allow to dry. Next, using the standard algorithm, soften and apply GOI abrasive.

Special points in use

It is not always possible to use GOI paste. For instance, treating gold-plated objects with this product will result in the irreversible loss of the precious layer and a rubbing down to a less noble metal. Generally, items composed of steel and nickel—aside from knives—are processed by means of a specialized machine rather than by hand.

A rag should be used to polish metal watches, but the mechanism must be taken out beforehand. You cannot use Paste Options Nos. 2 and 1 to start processing severely damaged surfaces. Under this scenario, the product’s flaws will worsen. Watch sapphire lenses won’t be handled. Simply put, GOI composition does not accept them.

Places of application

In addition to being used in homes to process silver cutlery, watches, and sharp objects like razors and blades, GOI is also being used in factories. In manufacturing, ferrous and non-ferrous metal parts are polished using GOI paste primarily in galvanic shops. Processing is done with specific felt-wheeled polishing machines.

GOI paste is an adaptable tool that can polish metal surfaces and jewelry, among other things. It’s the first choice for anyone trying to preserve or restore the shine of their possessions because of how simple it is to apply.

You can accomplish results comparable to those of a professional at home if you use the proper techniques. With the right technique and a little perseverance, you can achieve the desired finish on both small and large surfaces.

Adding GOI paste to your cleaning regimen will help ensure that your possessions remain well-maintained and new-looking for many years to come.
