Wood Bleach vs 99% Pure Oxalic Acid

[Jen]

For those of us who are using oxalic acid vapor to control mites, what is the protocol now for the purity of the oxalic acid granuals as opposed to wood bleach.

It was taught 10 years ago that wood bleach has additives, sawdust and other stuff, that is not good for the bees, and to be sure and buy 99% pure oxalic acid, of which I have only found on Amazon and not on the shelf.

I found it at the local hardware, but it is only lefal to use it from an authorized dealer with the approved instructions. To ust the hardware bleach is illegal.

This is legal.........
