chrome removal in Model Building Questions and Answers Posted November 1, 2016 Yes Super Clean (the Purple Stuff, etc.) has lye (sodium hydroxide) in it (same as in the original formula EasyOff). It is the lye which does most of the stripping (the other chemicals in Super Clean help too). I was also surprised that Super Clean has not been mentioned yet. It strips the metallic layer and the clear coat under it.. Keeping it the stripper warm also speeds up the stripping action. By warm I mean around 90-100 F.
