M.S.R. - Mold Stain Remover

I wasn’t expecting much, but I’m very pleased with its effectiveness. It has a strong odor but it dissipates. I’ve had black mildew/mold for several years. I followed instructions and most of it came off with considerable ease. I would recommend it

My parents builder used sanded grout in their shower, and what a pain it’s been to try to clean. After a little over a year and a half of trying to clean it, the grout was so discolored. They tried using several different popular tile/ shower cleaning products and event a spot steam cleaner. I purchased this after seeing it on Instagram along with the grout cleaner. This was the first product I applied. It was so easy to do. And, wow, the grout is the whitest, cleanest it’s ever looked. I’ll be buying the sealer next for them to apply now that the grout it clean. I’m attaching a photo showing the dirty grout next to the test spot I did.

Amazing product! I applied it a d expected to wait hours for ,hopefully, SOME results. I checked it in one hour and the stains were gone. I love this stuff!
