I've used brake fluid,super clean degreaser for years now....just want to make sure the super clean dose not dry on the bare plastic this may or may not leave a film on the plastic or haze. Never had ether one harm them beyond use again when stripping old paint off. I have had oven cleaner etch the plastic before though and wont use it anymore myself....the other two can handle about any paints depending on how old or used you chemicals are?
