I know that this has been covered before but cannot find the topic. Blue residue from a sticker needs to be removed. Can someone tell me the best way to do this? Many thanks

""Just like there are many metals, there are many plastics that are very different from one another. Overall, plastics can be divided into two basic groups:
Crystalline: Polypropylene, Polyethylene, Polyester (all types), Nylon
Amorphous: Polycarbonate, Styrenics (including ABS), PVC
The main ingredient in WD-40 is a light kerosene-like mineral oil, which is hydrocarbon based. Amorphous plastics and hydrocarbons don’t play well together: hydrocarbons will attack the chemical structure of amorphous plastics, breaking them down - essentially trying to “melt” them. In particular, Polycarbonate (PC) and Polystrene (PS). they are two named plastics on the WD-40 “do not use on these” list.
Crystalline materials are unaffected by the hydrocarbons in WD-40, you can spray them as much as you wish.""
The difficulty is knowing which type of plastic you have.
