Despite claims of the purity of 35% peroxide, there ARE also other
substances in it, from manufacturing contamination. H202 is so highly
corrosive it leaches some of everything it touches into itself. I saw
some analyses of what exactly the contaminants are in the 35% H202, and
so the claims of how awful the stabilizers in 3% H202 are has never
impressed me. Some brands of 3 % may have more or different stabilizers
from other brands though. And unless you test the 35% against the 3% in
the equivalent strengths in the SAME batch of CS it can't be said with
certainty that the reason for the difference is that one is
"contaminated" and one is not. Even with stabilizers, peroxide does
weaken with age so it could also be the freshness or not of the 3%. H202
is unstable even with "stabilizers" added, LOL.Which is why I liked it
as a cleaner for pet urine stains on carpet----------blot up the urine
so far as possible, literally pour on some peroxide (3%) walk away.
Cover with towel if pets will walk on the peroxide wet spot.
The peroxide oxidizes the organic molecules in the urine, and as it does
so it degrades into water itself, leaving behind no odor of its own, and
the vanishingly small traces of stabilizers. Yeah, I'm a lazy cleaner, LOL.
