This Product Really Works!

July 08, 2025

Recently moved into a new home with glass shower doors that were in great need of hard water mineral deposit and soap scum removal. Wow! This product is impressive. The first set of shower doors came clean with one application, and was followed with the Rain-X Shower Door Water Repellant. The doors are crystal clear once again. The second set of glass shower doors took a bit more work with four applications of Rain-X Shower Door Extreme clean, but the extra effort was worth it. The doors look brand new! My only regret was not getting a before picture to show how bad the glass doors looked, but I do have an after pic to share. This product is very easy to use too. I used a damp cloth to apply the cleaner, and worked in smaller sections while applying pressure and moving the towel in a circular motion, as directed. I then rinsed well using a gloved hand to wipe off any extra residue. Once rinsed, I wiped the glass completely dry to check for any areas that needed extra help. Although the product scent and fumes is not overly strong, definitely use with an open window or fan running.  Overall, this product works extremely well. I am very satisfied with the results, and how easy it was to achieve beautiful results.

Takes a fair bit of scrubbing to get the full residue off the glass. I use a soft bristle brush to scrub the glass, then rincse well. Added a microfiber cloth to get all the residue off. Now the water just runs off the glass not just staying there. Fantastic, and highly recommend.

Unbelievable awesome product!!

April 21, 2025

This is a miracle product. I've only bought Rain for my car's windshield before. I did not know this existed until I saw it on one of the whatnot auctions. I've tried different chemicals to get rid of water stains and buildups on my glass shower door and none worked except for this one. I have hard water in my area and do not have a softener installed so I get these water stains building up everyday. I followed the instructions and I could not believe it got rid of the majority of the lime and buildup on the first pass. I've uploaded a pic showing the small spot that I cleaned and treated on the right hand side. I also purchased the spray to protect the glass after this cleanup. AWESOME PRODUCT!!!

Great product for showers

March 04, 2025

I purchased this for our shower door and a mirror used for shaving in the shower. It works great. Just follow its directions and it will work and it appears to last quite a while before you need to reapply. Easy to use and if you don’t use too much, no streaks and easy to remove.

I did a rough patch on the doors and it actually works! The “cleaned” side is a little streaky but I’m hoping with a better cloth they will go away. I have had the hardest time getting the hard water spots off my shower doors and this took it off pretty effortlessly. I will definitely buy it again.

Great for well water stains!

January 05, 2025

We have very hard well water and this has helped to get build up off our shower glass. It has taken quite a few try’s to really get the stains off. But the stains have been on our glass for a long time so that’s to be expected. It’s easy to use. Don’t push too hard or you may scratch your glass (like I did). But if you lightly “scrub” it will be just fine. It doesn’t have a smell and it seems to keep my glass clear for a while.

I finally found something that removes water stains from my glass shower door. Be prepared to give it some elbow grease. It doesn't have a clean scent but that's OK because it does the job. Now the test...will it last?

When you've tried everything except replacing the shower doors

November 21, 2024

I've been battling with hard water stains on my shower glass for years. We ended up replacing the shower, and I was bound and determined to let them look like raggedy frosted glass. However with teens that cant seem to grasp the use of a squeegy ..... I'm not going to lie, Rainx, windshield stuff. I was skeptical at first, but at the end of my rope. However with one application as directed it made the shower doors look brand new!!!!!!! I would highly recommend this product!

Amazing Product

November 17, 2024

This stuff works. It comes out like toothpaste which you put on a damp cloth. It erases water spots with ease as you move in a circular motion like waxing a car. Rinse it off with water then use a squeegee. I haven't seen my shower glass this spotless since it was put in ten years ago. I was using a Mr. Clean Magic Sponge, but compared to this the sponge is worthless. This product is great.

Best product I've ever used to remove soap scum from shower doors. Wiped on and let sit for 15-30 min - it even dried in some parts....then went over with a wet cloth to suds up and then scrubbed - don't need too much exertion. Then rinsed and WOW - so clear. Very impressed. Went from what looked like frosted glass when we moved in to very clear!
