Is there something to buying "pure" oxalic acid from a bee supply place vs just picking up wood bleach from a hardware store? I've heard "oh wood bleach that's the wrong stuff" but its usually followed by "it may have other stuff in it."
From what I gather there are 3 reasons, correct me if I'm wrong
Wood beach usage not legal
Possible toxic by-products
Dosage is affected by purity of Oxalic
I'll probably get oxalic from the nearby dadant store in the future but I was curious if anyone had heard of anything negative in the wood bleach
