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.
... and the TLV (threshold limit value for exposition in working places) for trichloroethylene is lower than our nose sensitivity. USE IT ONLY OUTDOORS (try thinking it is formaldehyde).
