How can I clean baked on Leather conditioner off my instrument cluster lense?
try some alcohol followed by rubbing compound, use a very soft cloth with the rubbing compound, i used it on my headlights to get rid of the yellowing, and it didn’t scratch them at all, so it should be safe with your lens, don’t use any thing harsh like gas or bleach or anything with petroleum products, this will cloud the lens, and may even eat it up, also, try using the leather conditioner/cleaner on it again, but this time make sure you clean it off.
