It’s time to change the potassium hydroxide/water solution in my
Aqua Torch. I know the stuff is caustic–my question is, will it
damage plastic? At Harbor Freight I found a hand-pumped siphon pump
that would be perfect for removing the old solution from the internal
chamber of the torch. Before I try it and risk making a horrible
mess, will it be safe to use this with the potassium hydroxide
solution, or will the plastic dissolve?
