Household ammonia--which is far from being "pure ammonia"--is about a
5 to 10% solution and is certainly is stronger than what's in
Windex. I doubt that anyone here really wants to mess with the
strongest aqueous ammonia solution available, which is 28%. The 28%
ammonia solution must be used only in a _very_ well-ventilated space
(or expect to drive everyone out of your house and possibly find
yourself staggering and gasping for breath). The 28% ammonia solution
is available from blueprint supply shops--usually in one-gallon
bottles. I'd call that the "nuclear option".
