5. I remember the 1st time I was going to put hydrogen peroxide on a cut on my 5yo son's arm.

He was naturally worried it would hurt until I told him it was just water with oxygen in it. I took a small swig, swished it around my mouth and spit it out. He used it on every scrape since.

6. I have seen mouthwash

With hydrogen peroxide almost certainly..it struck me at the time. Must be at a very low dose like 0.001% w/v if that is the correct unit.

Edit: wow was I off..it is more like up to 3%
