For the small amount of cleaning of parts etc that I do I prefer to use 500ml spray cans of solvent. Since 111 Trichloroethane became Public Enemy No. 283 it seems to be difficult to find truly effective cleaners in spray cans. For instance, at present I'm using a product called TF-90 which I got from J&L. The details printed on the can say simply that it's a replacement for 111 Trichloroethane, without saying what it actually is. As a cleaner it's pretty useless; for instance, if I prepare a clean glass surface using meths or isopropyl alcohol then spray it with TF-90, a greasy residue is left after evaporation which is quite difficult to remove. I suspect that there is water in the product also. Sprayed onto a metal surface, there are many of what appear to be water droplets but I'll give it the benefit of the doubt that these may be condensation due to the cooling effect of the spray.
After that preamble, can I ask the group what cleaners they use, specifically in spray cans for direct use, and not of the spray on, wash-off-with-water type? How effective are they and are they completely residue-free?
I don't mind paying the money for the right product but want to avoid buying more of these expensive failures.
