Hydrogen Peroxide as a Natural Remedy: Benefits and Precautions

I've used brown bottle HP 3% to help disinfect ears after swimming in dirty seawater and to help eliminate some ear wax. I've always heard it fizzing away like it's boiling and doing something active.

I got some food grade HP 3% to nebulize and breathe. I switched to that for my ears thinking it would be better. But when I use the food grade I don't hear any fizzing noise so I don't have the confidence it's doing the same as the brown bottle HP. Does anyone have any comment to that?

Thanks,
Ron.
