There are many mold cleaning products out there but the one I have actually used in the past is the CLR Mold & Mildew cleaner, I’ve been using it for a few years now and I will say it does a good job on the tiles in bathrooms of course a decent size scrub is required lol; but with a little elbow grease if comes off very quickly just make sure to let the chemical set in for about 4 to 5 minutes giving the solution sometime to aggregate the surface and it comes off like magic! However, I am looking to find a better commercial solution. Any recommendations?
