What chemicals are the best paint remover?
In the past, paint thinner was the best and most available paint remover, everyone knew it as the best paint remover, but the fact is that the thinner is not suitable for removing paints and stains from all surfaces. Thinner is a strong solvent, but it is not suitable for places where beauty is important to us. For example, to remove paint stains in the kitchen, it is better to use other materials such as alcohol or acetone that have less power.
There are generally three general categories for different types of paint cleaners:
The first category, which is one of the most important, most practical, and widespread paint cleaners, is the category of solvents. In general, the mechanism of action of all solvents in removing and cleaning paint from surfaces is very similar.
Solvents affect the bond between the paint and the surface and it can loosen by interfering with, removing the paint from the surface.
Solvents can remove a wide range of paints based on oil, polyurethane, acrylic resins very well from wood and metal surfaces. Dichloromethane (methylene chloride), methanol, and toluene are in this category.
The second category of paint strippers is caustic chemical compounds. The mechanism of action of these materials is that by softening the dried paints, they cause them to flow and slide, and the paints can be easily removed from the surface.
caustic chemical compounds cannot have much effect on removing polyurethane and epoxy-based paints and are more suitable for cleaning water and oil-based paints.
The use of these materials on metals can cause the metal to darken, for which bleach can be used. Sodium hydroxide is the most famous substance in this category.
In order to clean paint stains from surfaces with these materials, it is better to give them half an hour to have their effect.
The third category is safer chemicals than the previous two categories. Biochemicals are usually made up of two components, a plant solvent component and a chemical component such as methyl pyrrolidone (note: you must be completely safe when using these substances).

Paint remover for metals; what chemical removes paints from metals?
The use of boiling water to remove paint from the surface of metals is a common method, but more precisely for brass and copper metals acetic acid or sulfuric acid can be used, to clean the surface of aluminum metal, the use of calcium carbonate is very effective. Tin is usually placed in a solution containing sodium carbonate.
Paint removers for plastics:
To remove paint from plastic surfaces, it is better not to use boiling water or a knife for this purpose. The best way to remove all kinds of paint from plastic parts is to use acetone solution, then wipe the surface with a tissue. Thoroughly clean and then rinse with water.
Does vinegar remove paint?
Using vinegar is one of the cheapest and easiest ways to remove all kinds of contaminated stains. Vinegar by its acidic properties can be very useful in removing tea and coffee stains, crayon stains, blood stains, and ink stains. It is enough to pour vinegar on the stain and let it come in contact with vinegar for a few minutes before washing in clothes (use vinegar solution and cold water).
Take a look at the ingredients and formulations of a paint remover:
In this section, we want to examine a kind of paint stripper formulation. As we mentioned, methylene chloride is a powerful cleaner for removing all kinds of industrial paints. In paint cleaning formulations, in addition to methylene chloride, the material Others are used that with the weight percentages specified below can create a suitable paint remover.
