A few weeks ago I posted a comment on the question Cleaning Mildew about hydrogen peroxide. I said:
Last week, a reader wrote asking, “Is there really phenol in hydrogen peroxide bought in drugstores? Ever since I read your article in Natural Home magazine about vinegar and hydrogen peroxide, I’ve bought lots of big bottles of drugstore hydrogen peroxide and used it (and vinegar) all over the house. I even used it on everything except my papers and clothes to wipe the mold spores off. (I hope you think that was a good idea!) But now I’m concerned that I should not be using that kind?”
I thought I should do more research on hydrogen peroxide, since I and others have been recommending it as a natural alternative to more toxic chemicals. For years I thought the drugstore type was 100% hydrogen peroxide because I had no reason to think it wasn’t. And I didn’t know until we started using it in our chlorine-free pool that other concentrations even existed.
