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.

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.

This works great. If the soapscum is heavy it will take some time. I used a plastic razor blade to help it along. After several weeks of applying it every 3 days I only have to use it once a week now.

It came in good condition. Wishing it was a bit stronger to cut soap scum streaking.

Love the product, bottles came apart.

I've tried many natural stone cleansers on our shower. This one actually works. Spray on a generous amount and walk away. Soap scum gone.

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!

What's wrong with the bottle and spray screws? As I spray for only few push, the bottle came off and it dropped on the floor... It spilled and I lost fare a bit... I thought I didn't make it tight enough but no matter how I do, at the end of the day, if comes off... So I needed to hold the bottom of the bottle when I sprayed... Otherwise, as advertised, it does remove the soap scales very well. It has very fine form and the form stays on the glass or stone surface for a while well. I left for a while and used normal spongy brush type of cleaning tool to scrub all surfaces through before washing form away with water. Personally I'm extra sensitive to any subtle smell and chemical stuff and I couldn't tolerate the smell of it at all, even wearing mask while cleaning so I don't think I will get next bottle. The spray and the bottle needs seriously upgrade, or maybe just I was the unlucky one.

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.

Took years of scum off the shower doors

I would give the product a 5 star review because it works well, except the spray bottle it comes in is terrible. The sprayer on top won’t firmly stay on the bottle, so I actually lost about half the product when the bottle separated from the sprayer. No matter how carefully you attach it, it still comes off.

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

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.
