A Surprising Way to Prevent Soap Scum Build-up on Glass Shower Doors

For the very first time, I’m having to deal with a glass shower door in the bathroom. That means I notice soap scum build-up more easily than ever before. A shower curtain tends to hide the soap scum just a tad longer than a see-through glass door. Since I see this soap scum build up every single day, I’ve been wracking my brain to come up with a way to make it less of a hassle to clean shower doors. I’ve found that wiping down the walls and door daily helps a great deal. But, I finally figured out way to make cleaning a glass shower door a breeze!


rain-x Yes, the Rain-X that you use on your vehicle windows.

Using Rain-x  to prevent soap scum build-up on glass shower doors.

Rain-x repels water.

Since soap scum is the junk left behind when the water evaporations, using Rain-x on your glass shower doors seems to slow down the rate at which that yucky soap scum can build up.

One bottle of the Rain-x pictured should last about a bazillion years (give or take a few!) if you only use it on your shower doors. That means it’s relatively inexpensive.

Rain-x is also super easy to apply. Here’s how:

Step 1

Spray the Rain-x on your glass shower doors. It should only take a few squirts to cover the enter door. rain x to clean glass

Step 2

Wipe with a clean towel cover the entire door with Rain-x and continue until completely dry. rain x wipe away after spraying on glass

Step 3

Spray the glass with water to test how the Rain-x works. rain x test using water

Step 4

Watch the water just bead up and roll away! Here’s a side-by-side comparison so you can see the difference on my shower door. rain x side by side comparison

Step 5

Enjoy several weeks (maybe even months) of soap scum free glass shower doors! Using Rain-X on my glass shower door has really saved me time and energy when it comes to scrubbing dirt and soap scum away. That means I have more time to find more cleaning tips to share on i Dream of Clean. Or, you know, something more fun like hanging with friends and family!

      I’m so glad! Well, not that you have soap scum :)

    I’ve also heard that using the Magic Eraser is good for removing soap scum. So, maybe this is a good 1 – 2 punch for the pesky shower surrounds and doors. Thanks for the tip!

      Ah, yes, I {heart} the Magic Eraser! It useful in so many ways!

    Plain old rubbing alcohol does the same thing as Rain X. You do have to use probably twice as often but for the price it works for me! I have used alcohol from day one on car windshields to house windows, mirrors and shower doors, works great!

    I know this is an old post, but still relevant if you have glass shower doors. I fill a spray bottle with 1/2 water and 1/2 jet dry or finish – those spot removing liquids that go in the dishwasher. It works like a charm and it even repels the water and helps with soap build up for a few days, it seams. I know I read this somewhere, so the original idea wasn’t mine…but thought it was good enough to pass along. Happy Cleaning!

    I hadn’t thought of the shower doors (mine are also new) but I’ve used Rain X on the mirrors in my house for a long time. Keeps them fog-free on chilly mornings when the pot starts to perk up steam and a hot shower is so welcome!

    How do you clean horribly scummed showe doors? Need help! Can’t stand them like this anymore.

  • Rick December 22, 2013, 6:10 pm

    If your shower doors aren’t textured or frosted glass, then “0000″ extra fine steel wool that has been dampened will cut through the scum and buildup.

    for cleaning soap scum try 1 cup vinegar heated in microwave for about 2 minutes on high and add one cup blue dawn dishwashing liquid, mix in a spray bottle and then spray on the soap scum and let it sit a few hours to overnight – works like magic!
