      Sodium Hydroxide is in fact lye. I believe "Drano" is also made of
Sodium hydroxide as well.. This is very caustic stuff and quite dangerous.
I have a friend that had severe 3rd degree burns from using this stuff with
both no protection and no common sense .
      Potassium Hydroxide is found in some paint removers( probably the
weaker water soluble kind) and is also very caustic . I had delt with a
company in Cleveland that made paint removers and would also sell
individual chemicals, but for some reason I can not remember their name
but they were on Spring Parkway..... They also sold 28% Ammonia and 99%
pure Glycerin very very cheap in gallon jugs or 5 gallon pails...
