Yeah, that's why I said you probably can't just go out and get them anymore in stores since I think they're considered a hazardous material now. I also used carbon tet and benzene when I was kid in the 60's when I collected stamps and currency, to bring out the watermark. (Maybe that's what's wrong with me now. Hee hee!!!!)
Sometimes the electrical cleaners I used were trichloroethane or trichlorethane based. Recently I use brands by Techspray and Chemtronics. I believe they use Dichlorofluoroethane. Check out Techspray #1690, it mentions nicotine. http://www.techspray.com/newinfo/1690.pdf -Clint God Bless Clint Hamilton, Owner http://OrpheusComputing.com ) http://ComputersCustomBuilt.com ----- Original Message ----- From: <[EMAIL PROTECTED]> Just a few comments on the cleaners that have been mentioned for the removal of cigarette smoke residue. (probably tars and nicotine). Benzene is on of the best cleaners I have ever used. It is also one of the most active and deadly carcinogens available. It is absorbed through the skin and by breathing the vapors. Do not use it without proper protection. Carbon tetrachloride is also a carcinogen and is also absorbed through the skin and by breathing the vapors. If you subject it to heat, such as cleaning a just soldered joint, you will get the sweet smell of "new mown hay". That is phosgene, a WW II poison gas. I think that in the USA ethyl alcohol is denatured by adding a poisonous aldehyde to it that has a boiling point a few tenths of a degree different from that of ethyl alcohol. This is so that you cannot distill out the ethyl alcohol from the untaxed denatured ethyl alcohol without also getting the aldehyde.
