I wear a face shield and nitrile gloves if I’m doing a roof, but downstreaming never…
And never a mask. Is it really that bad?
Oxalic I hate doing with anything but a roller. I’ll put on a face shield for that if I have to pump spray it on. Atomized oxalic is awful.
As far as environmentally safe, I always tell people it’s commercial grade bleach diluted down. It’s going to smell like a pool and it’s about as harmful as pool water if the process is adhered to.
