The commercial 3% is safe to use as long as you’re not ingesting it. It is a more practical, and economical choice for soaking, since it doesn’t carry the hazmat shipping restrictions.

Ah, but I do not pay hazmat shipping charges...I drive to my Amish friend’s place and pay $10 a gallon for the 50%, $9 for the 35%.
There is 28% hydrogen peroxide available in many swimming pool stores, at a reasonable price (but more than what I pay). We use hydrogen peroxide instead of chlorine for our swimming pool. Makes swimming healthy! This is ok for anything except internal use.
