I was cleaning the interior vinyl portions of my corvette last night and used Tricloroethane (also referred to as T 1.1.1. I think , you can buy it at Home Depot as a carpet / spot remover and I think it goes by the brand name Afta) to remove some spots that soap and water / Fantastic etc. wouldn't clean. It worked great, may be even too good ( I think it will take the paint right off the vinyly if you're not careful). This is a nasty solvent! Probably causes liver damage and cancer and I believe it desolves some types of plastics ect? I'm not recommending that anyone use this but with all the talk about Acetone and MEK I would like to know if this solvent is little better to use on vinyl when you need to use a very strong solvent degreaser?
