Re: Buying KNO3 -- Stump Removers

The guy with the rocketry site surmised that it was used to further
accelerate the decomposition process. I guess two oxidizers are better
than one. I'm pretty sure the product I have does not contain lye since it
doesn't have that "dry yet wet" feel and doesn't suds up. Lye aside, I'm
paranoid enough about the stump remover now, though, that I'll be searching
out another source. My current bottle's nearly empty and I wouldn't mind
having something that dissolves easier anyway.
