Test the any solvent on a less important part of your saw, such as a scratched up part of the bottom, inside a cover, etc.
I have a wide range of solvents, cleaners, etc., that I use for a variety of projects and applications. Some will ‘frost’ certain plastics, some will soften them, some can be used to weld them! Some will remove paint.
Different manufacturers will use different types of plastic or paint on different parts of saws.
I like to start with the mildest solvent (water), then progress through citrus-based cleaners, alcohol, paint thinner, etc. before going to acetone, lacquer thinner, etc. I also have ‘Goof-Off’, ‘Goo-Gone’, and some 3M adhesive removers. Kerosene is an interesting idea.
Different types of alcohol (isopropyl, denatured ethyl, etc.) can make a difference.
BTW, I keep some acetone in (labeled) old nail polish remover bottles from my wife, daughter, etc., which makes small amounts easy to use in the shop fro cleaning, adhesive removal, etc.
