Rain-X 630035 X-Treme Clean Shower Door Cleaner, 12 Fl. Oz, Formulated To Glass Doors - Easy Use, Removes Soap Scum, Dirt, Hard Water Build-up, Calcium, Lime And Rust Stains

I am very impressed with this product! It cleaned the soap and hard water stains off of my shower glass door. I used this combined with the Scotch Brite Bathroom Buildup Sponge. I wet the sponge with water and applied the glass cleaner in a circular motion twice then rinsed off with water. I was surprised how easily and quickly the glass was clean. Would definitely by again!

This stuff took off hard water stains that NOTHING ELSE could ! Due to not having a maid during the COVID era, tough hard water stains built up on my shower glass for two years. Tried everything I could find on the web to remove these stubborn stains (over 20 different methods, including using sandpaper) and NOTHING WORKED. Out of pure curiosity (and knowing I could return to Amazon) I order the Rain-X. At first, thought the product was defected, as I could barely squeeze anything out of the bottle ! But after I pulled the top off to see what the issue was, turns out this is sort of “polishing paste” and bottle was designed that very little of the product is dispensed at a time. BOTTOM LINE : OUT OF 12 COMMERCIAL PRODUCTS AND 8 METHODS USING COMMON HOUSEHOLD PRODUCTS, THIS IS THE *ONLY* ONE THAT TOOK *ALL* OF THE STAINS OFF ON MY SHOWER GLASS - HIGHLY RECOMMENDED - 5 STARS ⭐️⭐️⭐️⭐️⭐️ !!

This is the best thing I’ve used. I squeegee my shower after every use and I still have tons of soap scum build up. I’ve used CLR, vinegar and baking soda, and bleach spray. This stuff you literally wipe on and wipe it off. No elbow grease involved. definitely worth buying

I was skeptical this would work after spending several hours scrubbing my water stained shower glass with vinegar and baking soda to no effect. To my surprise the rainx product completely cleared up my cloudy, spotty glass. Took a lot of elbow grease but works great.

TLDR: It really works on really tough really old spots! I tried all kinds of harsh chemicals and abrasives on my new shower doors with no luck. Best I found was scraping with a razor blade and regular scrubbing with steel wool, but still left a lot of spots. I thought they were going to be permanent. One expert website recommended wet sanding with 3000-7000 grit sandpaper, which I luckily tried on a small area first because it scratched the glass but did not remove the spots. So I had my doubts when reviewers claimed this product removed old soap scum and tough water stains. Well I was blown away by the results. Not only was my glass crystal clear but it was effortless. It only took a pea-sized drop on a wet sponge per side of glass. There was no harsh fumes or scrubbing. My tip is use lots of water. The directions recommend a damp cloth but it felt gritty and did not go on evenly so I kept adding water until it was dripping wet. Also use lots of water when rinsing off and run a clean sponge or your hands over the glass or it may leave a hazy film behind.

It worked pretty well but was a lot of work. Will keep looking for a better product.

You get a workout buffing this on, and then wiping it off. Used on glass shower door with hard water haze. Glass was clear and spotless once I applied it.

It makes it super easy to clean! There are still a few spots that did not come completely clean. But it is a great product. See before and after!

This one is great, helps keep my shower glass clean

Been trying to deal with calcium deposits for ages- tried lots of stuff. This came the closest to clean. Still a bit cloudy, but SO much better!
