This remedy works great! I had been fighting mold and mildew in the shower for years. I had mold developing on my shower ceiling and I would normally use bleach in a spray bottle and had to wait for it to dry. I mixed 50/50 of peroxide and water, sprayed the ceiling, waited 10 minuted and it wiped right off with a sponge. I'm telling you this really works. I have never seen the shower so clean!
