Aircraft paint remover is methylene chloride. It is a solvent that won't attack aluminum. Other paint removers are alkyline such as potassium hydroxide. You can use either on steel or cast iron. Use the methylene chloride around glass, aluminum, copper but not rubber or plastic.

Good methylene chloride is hard to find. Store bought stuff has been diluted with other solvents like acetone. Pure MC has a boiling point somewhere around 75 degrees so it is safe to say that all MC paints removers have been diluted or adulterated. The consumer stuff is more so. I used to get the good stuff in five gallon metal buckets from a company that sold building restoration products. I would expect the aircraft formulations are good as well seeing that they are intended to be used by professionals.
