Hi Bob,
Carbon Tet, trichloro ethylene, perchloroethylene, all chlorinated hydrocarbons which have fallen foul of H&S as has benzene.Dichloromethane, Nitromors is the best chlorinated hydrocarbon still available.
Chloroform and ether , you cant buy as restricted use because of its ability to knock people out.
Acetone still used for nail varnish , can be quite good on inks.
Methylated spirits is ethanol with some methanol added to stop all but the most desperate from drinking it !, probably part of eco spotter, from what Ken was saying.
Amyl Acetate is in Chemspec POG
Oxalic acid is a reducing agent I currently use sodium metabisulphite but yellows are a problem, so will have to try.
Glycerine haven't tried on coffee but I have some so will.
Cheers
Doug
