  • Repels Water Perfectly!
Size: 16 Fl Oz. (Pack of 2)
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. I first used the Rain-X Shower Door Extreme Clean, and was followed with the Rain-X Shower Door Water Repellant. The doors are crystal clear once again. This product works so well that the water just beads right off! I also squeegee after a shower to ensure clear glass doors. This product is very easy to use too. I used a clean cloth to apply the repellant, and worked in smaller sections while applying pressure and moving the towel in a circular motion, as directed. I then waited about five minutes for a light haze to appear, and applied a second coat, as directed. Once the haze appeared again, I buffed with another clean cloth. Beautiful! 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. ... show more

  • The BEST bathroom cleaning hack EVER!!!
Size: 16 Fl Oz (Pack of 1)
The media could not be loaded. Have you ever used RainX products on your car’s glass surfaces? Well, this stuff is basically that, but for your bathroom’s glass (and other) surfaces. (And if you haven’t tried RainX on your car… I highly recommend you do. I live in WA. We tend to get a LOT of rain. RainX is awesome stuff!) I hate having to squeegee my shower. It’s also usually the last thing on my mind. I’m either running late and don’t have time to squeegee… or I’ve taken a long time unwinding and relaxing in a hot shower. When I get out… I want to wrap up in a soft robe, climb into bed, and sip some hot tea. I don’t want to squeegee the shower stall. But an ounce of prevention is worth a pound of cure! And when I don’t squeegee… a few months down the line and I’m scrubbing, trying to get rid of hard water stains. I’ve also found that even when I do squeegee regularly, I am still battling hard water stains. Meanwhile, the shower looks awful. We’ve been in this house for 7 years now. There are a lot of random niches for hard water stains to get missed over time. So, I started researching ways to be lazy and still have a clean bathroom. That’s when I stumbled on RainX for shower doors. Now, I won’t sugar coat it… it took me a while to apply the product per their directions, wait for it to dry, reapply it, let it dry again, and then buff it off the surface. (I’ve found if you apply it kind of liberally the first time… and give it sufficient time to dry… you won’t need to reapply it a second time - I’m lazy, y’all! I look for shortcuts!) I went all out! I put it every surface I could! The product does have a strong odor. I didn’t find it too overwhelming or too caustic. However, if you’re sensitive to odors or chemical smells… plan on using a mask. I kept the bathroom fans on and I was fine. It’s not difficult to remove, but it will take several passes. You just keep buffing in small circles… one area at a time… and then move on. It’s just like turtle waxing a car. Or The Karate Kid… wax on… wax off! And you can do more than just glass… I use it on my shower doors (inside and out) my shower surround, the bath tub, the sinks, the faucets (all the chrome), and especially the mirror. When you’re finished, you won’t have to squeegee… water just beads off surfaces. The tub is slow to develop a ring around it… and when it does… it very easily wipes off. The bathroom mirror will still fog up, but it’s MUCH quicker to clear up… and toothpaste splatter droplets just flake off when you barely touch them with a paper towel or microfiber cloth As evidenced in my video, if you end up with fingerprints or something else on your glass surfaces… just use a dry paper towel or microfiber cloth and polish whatever it is right off the surface! Using it on my shower surround and trim has prevented the accumulation of hard water stains. (See pic.) The best part? It lasts for 4-6 months with regular usage (two persons, occasional guests, and monthly doggo spa days). When I start to notice a decrease in how the water is beading up… I just reapply to that one area. Overall, the amount of time I spend applying the RainX is WAY LESS vs squeegeeing and having to do regular scrubbing to remove hard water stains, windexing the mirror, polishing chrome, etc. It makes my bathroom almost self-cleaning, which I absolutely LOVE! I do still break out my dish soap and vinegar filled dish soap scrubber and run it on the shower and tub floors, and in a few other areas. And to date, I haven’t discovered a self-cleaning toilet, so I still have to clean that… BUT… I won’t go back to the old method of scrubbing and squeegeeing! RainX is an all around great performing product! ... show more

  • Does Not Work
Size: 16 Fl Oz. (Pack of 2)
Here is a classic case of why you shouldn’t trust that a product has thousands of great reviews, if it seems too good to be true. My shower door is brand new; it was installed just a a few weeks before I purchased this Rain-X product for shower doors. The photo is a close up of the shower door, just one shower after the product was applied as directed on the thoroughly cleaned glass. When it was applied, the odor was horrible and the film left on the door had to be buffed out twice. Water did not bead up, as you’d think it should with way this product is described. The resulting water stains were no different from what they were like before I used this product. I also learned that you can not easily return this product for a refund. You have to contact the company that makes it directly, and they require a you to fill out an online form for a refund. The form is faulty, and so, tired of going back and forth with the company by email, I will give up on the refund and take this stuff to the local hazardous waste facility for disposal. ... show more
