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!


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

    Oh my gosh that is great! I am so going to buy some. We have horrible soap scum in the master shower. Thanks so much!!

    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!

    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!

    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!

    I use liquid shower soap…and never have the soap scum problem. I do however, have hard water
    stains. I dry my shower door with my towel (after dying myself) which helps keep the hard water stains at bay. Then, occasionally clean it with vinegar/water/dawn soap spray mixture.

    I just had some beautiful glass shower doors installed in my home, and now I need to learn how to best keep them clean. Obviously prevention is the best way. I have never thought of anti rain products, but it makes sense that they would repel water in the shower as well. I also agree with this where it says that the best prevention is keeping it clean. Thanks for sharing this information!
