Black Diamond Stoneworks Natural Stone Soap Scum Remover for Showers, Glass Doors & Acid-Free. - 1 Quart

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.

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.

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.

This product did remove soap build up from my natural stone shower but only in the grout. It did nothing to remove soap buildup or hard water stains from the stone itself. I even left it on for over an hour and used a power scrubber.

Amazed how well it worked

I ordered this product because it had gotten very good reviews for both efficiency and ease of use in removing built up soap scum from stone tile in showers. I have a stone tile floor, made up of actual stones in thick grout. It had accumulated a lot of soap scum that shows up as white around some of the stones, especially around the drain. Based on the reviews I read, I looked forward to using this product. My husband and I worked together, followed the directions,, used a scrubbing brush after waiting a couple minutes for the product to soak in, and we scrubbed away multiple times, and the white remains. We are super disappointed with this product!

I bought this to clean my shower tiles and floor and not only does it clean the shower so well but it cleans the glass does better than windex! I have found it also works great on my kitchen counters! I have used other cleaners and Lysol wipes on cointers and then wipe with a wet paper towel and still see dirt but after using this the paper towel is clean! The other day I couldn’t get my stainless steel stove clean with the stainless cleaner so I tried this and whatever it was (grease stain or something) came right off and left it sparkling. I highly recommend this cleaner and it doesn’t have any harsh smells to it, just smells clean! I will definitely continue to purchase this for most of my cleaning needs!

Trabaja perfecto en mármol negro, no deja manchas

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.

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.

Didn’t remove any soap scum

Cleans well and easy to use but seem too expensive but I'll still use it.

Took years of scum off the shower doors
