Review of means for degreasing surfaces from different materials

Painting surfaces is an important step that can have a big impact on the final finish’s durability and quality. Grease, oil, and other contaminants must be removed during the degreasing step of this procedure. This guarantees that the paint will adhere correctly and won’t chip or peel too soon.

Certain degreasing techniques and products are needed for different materials, including plastic, wood, and metal. The incorrect cleaner can cause surface damage or leave behind residues that impede painting. Thus, choosing the right degreasing agent is essential to getting a paint job that looks good and lasts.

This article will examine several methods for degreasing surfaces composed of diverse materials. We’ll examine frequently used products, their efficacy, and proper application techniques. Knowing how to properly degrease a surface, whether you’re working on a car, furniture, or household item, can make a big difference in how well your project turns out.

The need to degrease the surface

Surface pollution varies widely in intensity; for a weak impurity, it is 1 g/meter square; for a strong impurity, it is greater than 5 g. No matter how severe, degreasing must be done before repair work can begin. Failure to do so will result in fat and dirt reducing the material’s adhesion when finishing the surface, which will lower the quality of the work.

It is not worthwhile to estimate how long the product will be used for—it will be brief. Degreasers must therefore be used when processing materials such as glass, wood, metal, plastic, and other coatings.

Degreasing agents

In the event that someone chooses to degrease a surface in their home, apartment, or country, any appropriate solution is applied to a napkin devoid of microfiber pile or another appropriate material.

If prepping is necessary before painting an automobile’s body, this approach is inappropriate. Of course, it’s best to leave car cleaning and painting to the pros who can do the job quickly and effectively. In certain situations, you can use your hands to remove the fat layer and shield the body from rust.

White Spirit

The White Spit organic solvent is almost universally owned by drivers, and it’s frequently used in repair shops. After applying alcohol in a solution with orthophosphoric acid to eliminate pollution residues, the white spite is meant for primary body processing. Substances are combined in a specific ratio to create the solution.

You can safely clean the car’s details with white spirit because its composition won’t damage the metal. Another benefit is its low cost. The strong smell is a drawback. Some auto owners use trichlorethylhen instead of solvent, but this should never be done on aluminum alloys as it increases the risk of fire.

Gasoline, acetone, other analogues

These goods are all effective fat, mastic, and paint solvents. Although the structure of diesel and kerosene is fairly dense and challenging to clean, their composition makes them suitable for degreasing.

To remove all traces, the solvent will need to use a reinforced sink after using kerosene and gasoline. Acetone should not be used for car processing because certain types of it can damage the metal.


Antilicon is a colorless liquid used for oil, fat, and silicone removal washing. This material is intended to eliminate pollutants from plastic, steel, aluminum, stainless steel, galvanizing, and varnish coatings.

After applying it to the surface, it is cleaned with a paper towel or dry rag. Working in a ventilated room with gloves and a mask is required.


Antistatics can be used for surface speeding prior to painting. Doing this on plastic is particularly effective because plastic has the ability to electrify and attract dust. The fat film will be challenging to remove, but it becomes much simpler after the plane has been treated with antistatic.


This group uses alkaline-effect detergents in their preparations. can remove any kind of pollution, even fat. Typically applied in daily life.

A roller is used to clean concrete and plastic before applying it. Use alkalis very carefully before staining the car. After cleaning the surface, give it a good rinse with water and let the parts dry. Strong foaming and copious amounts of means ought to be prohibited.

Ultrasound and other methods

The use of solutions in conjunction with ultrasonic field baths is the new technique for cleaning surfaces. This technique works well for degreasing small parts with intricate bends, uneven surfaces, and multiple mechanisms (hours, for instance). The method is not appropriate because large products are expensive.

An electrochemical degreasing method exists. Additionally, it is done in the baths, where electrodes supply the gas. Chemical solutions are used in conjunction with current to clean the surfaces. Usually, industry uses this kind of processing for production.

Than to degrease plastic

One of the biggest classes of materials is plastic, which comes in a variety of forms. Certain plastics, gasoline, acetone, vinegar, and other materials derived from these substances will instantly lose their usability. Additionally, plastic is not always a good fit for universal compositions.

Only specialized tools that are suitable for rubber and plastic and can be found in the right stores are used on the plastic components of cars. You can try applying the White Spit on material in home settings. Since vodka effectively degreases most products, Antistatik is 100% safe.

The following is the process for degreasing plastic prior to glueing it:

  1. Suffle the dust with a rag (dry), if necessary, wash it from obvious dirt, dry.
  2. To impregnate a rag with a solvent.
  3. Gently wipe the surface.
  4. If there are doubts, first try to rub a small section of the product.

We degrease the metal

Apart from oil and grime, metal frequently has residues of paint, sealant, and rust. Choose gasoline, acetone, and white spite for processing metal.

The steps are as follows:

  1. Remove rust, paint, remnants of sealing with a grinding machine, manually, grinder, sandpaper – in any convenient way (a bath in the house is treated with sponge with soda). Significant areas of area is best cleaned with a power tool.
  2. Moisten a rag with a solvent, treat the product until completely cleaned. If the parts are small, you can simply immerse them in the solvent.
  3. After complete drying, you can use primers, paints. Those areas that are not subject to painting should be closed using bilateral tape.


Prior to painting, wooden products should be free of paint and varnish. Use a metal brush, sandpaper, and a shirt to give the tree a thorough cleaning in the first step. If the paint is deeply eaten, the latter is used to remove the top layer; with excellent work, the surface cannot even be degreased.

Specialized products and all-purpose solvents are applied to wood using a roller. Using gasoline is illogical. It’s simple to clean the surface after applying the composition and then start staining.

Appropriate degreasing is necessary before painting surfaces in order to guarantee a durable, smooth finish. This review examines several degreasing techniques and products, emphasizing how well they work on various materials like wood, plastic, and metal. We compare the benefits, drawbacks, and best practices of industrial-grade solvents and household solutions like soap and water, offering helpful advice to help you select the best degreaser for your project. This tutorial will assist you in consistently achieving a faultless paint job, regardless of your level of experience.

Smir of glass for glass

Glass products can be dissolved with acetone, alcohol, or any other solvent. Such chemicals will not harm this material. You can use any all-purpose solvent prior to adhering the glass.

Material Recommended Degreasing Agent
Metal Acetone
Plastic Isopropyl Alcohol
Wood Mineral Spirits
Glass Ammonia Solution
Concrete TSP (Trisodium Phosphate)

Selecting the appropriate method for degreasing surfaces is essential to getting a superior paint finish. Different materials, like wood, plastic, or metal, have special qualities that call for different approaches to degreasing. Better paint adherence and durability are ensured by proper surface preparation, which lowers the possibility of peeling or flaking over time.

Solvents such as mineral spirits or acetone work very well on metal surfaces. Grease and oils are swiftly dissolved by them, leaving a smooth and clean surface for painting. However, because of their strong fumes and flammability, it’s imperative that you use these in well-ventilated areas and adhere to safety precautions.

Often, softer degreasing solutions are required on plastic surfaces to prevent damage. One popular option is isopropyl alcohol, which cleans well without wearing down surfaces. Furthermore, there are specialist plastic cleaners that are made to specifically address different kinds of plastic, guaranteeing a complete and secure cleaning procedure.

Wood surfaces call for a more careful technique. For light grease, a solution of mild soap and water will do; for more tenacious residues, denatured alcohol is an excellent choice. After cleaning, it’s critical to let the wood air dry fully to avoid moisture influencing the paint job.

Choosing the best degreasing technique requires an understanding of the unique requirements of each material. In addition to improving the finished look, this meticulous preparation process increases the paint job’s longevity and durability. For optimal results, always put safety first and adhere to the manufacturer’s instructions.
