To make that clearer, I mean places that sell to beauty parlors. Most will sell to individuals, though some require buyer to be a licensed beautician.

You can also get high percentage hydrogen peroxide at beauty supply shops in the US. It's very inexpensive.

Greetings! Your results sound impressive! Is 35% FOOD GRADE peroxide the same as the chemical you use? I see food grade is readily available...

As per your request I've created a new album "Beefys Stuff" and put a couple of pictures of the board there. It's hard to get a good photo at night time with just the house lights, they either create reflections or shadows. Hope they are OK.
