Not sure about that Kevin?
Goo Gone, although it does contain some petroleum distillates, I believe it is mostly a citrus extract. I dont think it is near as harsh as Zylene. I'll Have to read the bottle.... 3M also makes an adhesive residue remover that is very similar to Goo Gone in a aerosol can (have it right in front of me), it list "Citrus Extract" on this as well....
