I have a wonderful ionizer and I fill a glass bowl with the 11.5 Alkaline Water to soak my veggies (and meats) in it. It not only kills any microorganisms, but it makes everything so flavorable.
I also wash with it; laundry, floors, etc. and the good thing is that it's WATER.
However, this doesn't help you..I am just telling you what I do and that it is incredibly wonderful.
BEFORE I got my machine, I used the food-grade Peroxide, and following the directions for a food wash, I cleaned the sink, then filled with water and put in so many capfuls. It also worked very well.
I don't know about any soaps though, other than whatever is sold at the health food stores..
