All over the globe, Ammonia and Acetone are the two widely used chemicals to remove paint from the metal surface.
Chemical Strippers
These include caustic pastes and semi-paste solvents: Caustics usually contain lye and work by breaking down organic molecules in the paint responsible for its adhesion properties.
Dimethyl sulfoxide (DMSO) has become more popular since it has a low level of toxicity, making it a safe replacement for methylene chloride and NMP. Opting for a safe active ingredient like DMSO or a manual paint stripping method will be far safer than risking NMP or methylene chloride.
Paint strippers are solvents that soften the old finish for easy removal. They're available as a liquid, gel or paste and are effective at removing paint from wood on large projects, curved shapes and fine details. Using paint stripper on rounded surfaces and tight areas is often easier and more effective than sanding.
Acetone, a powerful solvent, can quickly strip off the wax layer and penetrate the clear coat. Once through, it begins to eat into the base coat, leading to fading, discoloration, and peeling. If it reaches the primer, further damage occurs, weakening the car's protective shield.
Sanding is one of the most popular methods. It is usually used to help smooth out old paint, remove dry streaks and uneven paint buildup, and ensure that new paint adheres well. In order to remove the paint from wall you can use sandpaper, a sanding block, or a power sander.
Pressure washing is one way to remove paint from wood, metal, concrete, and other exterior surfaces. Because of the high pressure levels, it can be very efficient and can drastically cut the time to complete this task. As with all power equipment, always wear safety glasses and closed toe shoes.
Examples of paint thinners include turpentine, acetone, naphtha, mineral spirits, toluene, lacquer thinner, alcohol, and xylene. These powerful solvents break down oil-based paints, primers, and stains, making it easier to strip paint, clean tools, and thin paint to fill a paint sprayer.
Currently methylene chloride and N-Methylpyrrolidone (NMP) are used in the majority of paint removers in the United States. Methylene chloride has been the preferred solvent for use in paint removers for seventy years.

To correctly strip old paint, you should work with a power washer with a psi of 2000 or higher. Even starting out at 2000 probably won't do the trick and you'll need to set the psi closer to 3,000 for effective paint stripping. Also important is choosing the right spray nozzle for the jobs.
Broadly, acetone is an effective paint stripper, even after the paint has dried. Acetone will strip and/or dissolve other things, as well. It can remove super glue, for example, but use caution depending on what the super glue is on — acetone can easily damage varnished wood.
