Black Diamond Stoneworks Natural Stone Shower Soap Scum Remover Spray. For Cleaning Bathtubs, Glass Doors, Tubs, Travertine, Marble, Tile. Heavy Duty, Safe Acid-Free Cleaner. Safe for fixtures.

I was nervous to try anything that could possibly damage the dark slate tile in my bathroom shower, but I had nothing to fear after all. It worked so well! I did what the instruction said, and I scrubbed a little on the harder spots. I’ve been looking around for a while for a natural product that could work. I may need to do one more scrub on a few spots, but it surprisingly worked great! I will definitely be buying more when I run out. No more ugly white soap scum.

I was so sceptical of purchasing this product as all others I have tried are so toxic and work poorly and didn’t want to waste my money again. I wish I had taken before and after photos . The first go around was amazing and going to do another as this shower needed major help . Well worth the money.

Just know that this doesn’t smell good. But, that doesn’t matter to me because I have been trying for many months to clean off the soap scum off my black ceramic shower walls. I wish I would have taken a before picture, but I really didn’t believe this would work. I have tried every type of cleaner imaginable and nothing worked. The directions say there is no need to scrub, but I did use a soft microfiber sponge. To my shock, once the walls dried, 90% of the soap scum was gone. Most of it was on the lower walls where the soap splashes up, but I did use it on all the walls. I did a second cleaning in the lower areas and now 100% is gone! No more white soapy looking streaks. I am shocked and very happy. I had given up hope that anything would work. I will continue to use this weekly.

I was tired of fighting with soap scum. I sprayed this on my tub and let sit for a few minutes and washed off. It worked well. I use it once a week to maintain. It is quite a strong smell.

Works best if used regularly to avoid build-up. To remove built up soap or hard water it isn't great. (Takes a lot of applications.) Doable but not as good as I had hoped. However it truly has proven safe on many surfaces.
