My sister is veterinarian and told me the same. It is used to wash/clean
big animals foots. Like horses or cows (i think already said this here).
But asking in a supplier got 'that's too acidic, don't have'. Maybe
asking to a veterinarian that only treats horses.


Also from jj_winkel on 26 apr 09 
"Here in France it is easy and cheap enough to get "masonry" grade H202
(35% in weight or 130 in volume) used for wood bleaching and stains
removal"


Calling to the companies that package the acids, acetone, caustic soda
and so that i buy at the drug/hardware store (indicated in the package)
is one thing i never tried.
