I was reading an article today which claimed that exposure to WD-40 can lead to cancer. WD-40's website naturally denies this, saying their product contains no "known" cancer causing agents...while saying the specific ingredients are secret. Another website claims it's aliphatic petroleum distillates and petroleum base oil in aerosol..whatever that is. Anyway, I know I've gotten the stuff on my hands and maybe breathed a little vapor from time to time (while working on the Porsche not huffing it mind you). Does anyone have a chemical engineering background? Maybe I'm just paranoid
