I have to admit however, I never knew that until a few years ago. I thought mildew and mold were the very same thing! Kind of scary knowing I might have been touching stuff that could have made me very sick. I also didn’t bother to clean it up because I didn’t think it was dangerous! I know there are a lot of products out there called mold and mildew removers, but I wonder how many people realize that there’s more than one type of mold? I hope they know! Most of the mildew I’ve found comes from my shower wall. Pretty common I think! I do like the idea of just making my own products for simple things like mildew. Much more economical and better for the environment. Baking soda is number one on my cleaning list! Love the stuff! It’s a good abrasive for clothes too!
