Where did he get a can of that stuff?? Cleaning agents, wether domestic or for commercial use containing tetrachloroethylene have been outlawed for years. Personally, I like the old product better than what we're offered these days - it was so much more effective but the dangers were not only as described in the attached but in repeated contact with skin was a hazardous carcinogen. It was a great ant and wasp killer too - immediate death on contact.
