Well shit, I always preferred the old fully chlorinated stuff because it works better. When you say "chlorinated" I assume that means it contains chlorine, which isn't great, but is more an issue for chemical burns than anything, so you wear gloves and eye pro and don't worry about it. I never looked into it. I've probably inadvertently exposed myself to a /ton/ of TCE working on cars and other mechanical things. I buy brake cleaner by the case...
