Really? 50%?
I have 35% food grade, and a drop of that has lifted the varnish off of our kitchen table!
Or did you mean a 50% dilution of the standard 3% commercial product?
“Really? 50%?”
Yes, I have both 35% food grade and 50% food grade. I get it from my Amish friend. He buys it by the truckload in 50 gallon drums. Your 35% used not diluted would work as well as the 50% not diluted. We do dilute it for other household uses, to 3%. If I were going to soak my foot or my hand in peroxide, I would do it in about a 2% solution. When we do a whole-body soak in peroxide in the tub we usually use 1 or 2 cups of the 50% added to the water in the tub.
We haven’t bought any commercial 3% peroxide in years. And btw, that is not ‘food grade’.
