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).
