Re: Kodachrome/mold
FYI, 1,1,1-trichloroethane and trichloroethylene are different compounds. The former has three chlorine atoms attached to the same carbon, while in the latter, one carbon has one Cl and the other carbon has two. Also, the C-C is single bond in the former, and double bond in the latter. -- Ryuji Suzuki "Strange how people who suffer together have stronger connections than people who are most content."

There are better solvents for dirt, if you can find them, such as 1,1,1,trichlorethane, now hard to find because it is an envrionmental hazard. > > Richard, > Is this the same as trichlorethylene? If so, Home Depot or hardware stores sells it under the brand name of Sunnyvale or Sunnyside or whatnot, only about $23 a gallon. > > I use it for hand coloring BW prints--it is the same as Marlene solution sold in Marshall's kits, but a heck of a lot less expensive. David Lewis uses it to clean his bromoil brushes because it leaves no residue. Outside, of course. But don't store in styrofoam--it'll eat right through the bottom. It is apparently the same stuff used in dry cleaning or some such thing. > Chris > >
