This method has drawbacks: firstly, this way it is possible to remove paint from not all surfaces, even heat resistant ones. It will not be possible to remove the paint from the plastic, it can deform when heated.

This method removes the paint with a tool, electric or manual. Of course, it is possible to remove paint with a hand-held tool only from small surfaces, but in order to cope with large surfaces, you will have to use an electric tool (a "Bulgarian" will do). If the question is how to remove paint from metal at home, then this method can easily cope with the task. If there is no "grinder", then you can use a regular drill.
Using a power tool to remove the paint is even easier than the previous method. The working part of the tool must be pressed to the paintwork surface, and gradually moved, based on the wishes of the degree of cleaning.

The advantages of this method include versatility, thanks to which the most resistant paints are cleaned, such as varnishes, heat-insulating enamels, resin-based paints and nitro-paints.
You can remove the paint with the help of modern tools - special chemical compounds. You can help a variety of solvents, alkalis or acids.
The tool is applied for a certain time, depending on the power of the composition, usually the procedure takes from ten minutes to half an hour. After a while, the paint is removed with a spatula, and the surface is wiped with ordinary water.
