Rain-X 630544 X-Treme Clean Shower Door Cleaner, 12 Fl. Oz, Formulated To Glass Doors - Removes Soap Scum, Dirt, Hard Water Build-up, Calcium, Lime & Rust Stains (Pack of 2)

Must have! If you’ve used it on your car you know this product will be great. It cleans amazingly and if you partner it with the spray after it will last for days even weeks. The water beads up and slides right off your shower glass and keeps it looking great! The quality of the product is everything you expect.

i always hate to clean glass shower doors. now i'm okay! it actually works. follow the directions for clean, clear glass!

This is the only product I have found that will remove hard water stains on windows (from sprinkler system) and shower doors. Takes just a little elbow grease and a scrubby sponge and the glass is completely clear again. Great cleaner!

It did clean the glass but did not remove the water stains. I scrubbed and let it sit, just did not do what I bought it for.

takes a lot of muscle I do not not haveso,e of the hard water spots have disappeared, but still a lot to dissolvewill have to hire someone to do the task

This product is incredibly Great and so affordable! Love it! I have (2) bathrooms with glass doors!

First picture is before, second is after 2 applications. It’s better but still lots of water stains. I followed the instructions to the tee and used serious elbow grease. Waste of time, sweat and money.

Rain X works well. Easy to use and remove especially if you have a handheld component to your shower. I’mNot sure how often I should use it yet.
