I'm just gonna throw in my 2 cents here - I use Ostofresh. Just a couple of drops will do ya. It is covered as DME, just like my supplies and can be purchased thru your supplier. If they don't carry it, ask them if they can order it in for you.
I keep saying that I am going to try the peroxide - maybe I will give it a try over the weekend. Like teaching an old dog new tricks!!! Just gotta try it.
