To remove Armor All... Mineral Spirits (you can get stink free for more $) or Kleen Strip's wipe down prep is actually called Prep-All. Everybody always says Preps-all but there's no S in there. Bugs me. LOL! Both are safe for plastic.

FYI, Purple Power, Simple Green, etc. can leave a film just because they are such strong degreasers, it's the nature of the product. Good for heavy cleaning, bad for paint prep.
