Soap scum on glass shower walls and doors is an unsightly sight, which is why people love this cleaner from Rain-X made specifically to tackle that job. It’s only for use on glass surfaces, so you can’t use it to clean your entire bathroom like some other cleaners, but for gleaming glass, this is the one for the job, according to hundreds of customers. It’s a cream rather than a spray, so you wipe it on and then wipe it off along with scum and hard water stains.
Customers say it works well, even when nothing else would. It may take a bit of elbow grease for especially stubborn scum and water stains, but they say it’s worth it for “dream clean glass.”

Customers say it works amazingly well, and that a little goes a long way. Many have posted before-and-after pictures on Amazon, which show impressive results. “I can see out of my shower now!” one enthusiastic reviewer wrote.Continue to 5 of 8 below.

Scrub a dub, dub, no one wants to take a bath with soap scum in the tub. This Kaboom cleaner promises to make sure your bathtub is nothing but clean. It uses OxiClean to get the job done and take out grime, scum, stains, and other deposits. Beyond the tub, it works on tile, grout and sinks too, so you can use it to clean your entire bathroom.
While some say the smell can be a bit overpowering, they say the clean it produces is amazing. Many say they were skeptical after seeing commercials for Kaboom on TV, but became believers after using it in their own bathrooms and seeing it make soap scum and other grime disappear.

Getting rid of soap scum is one thing, but this Tilex spray keeps it from building up in the first place. You don’t have to scrub or rub, just spray it each time after you take a shower, and that's it. It forms a protective barrier that keeps soap scum, mildew, and other unpleasant substances from sticking around. It can be used on most surfaces, though it’s not recommended for natural stone, marble or brass.
Customers say it’s easy to use and cuts down on cleaning significantly when you use it regularly. Many report that the smell is pleasant too and not nearly as overpowering as some soap scum removers can be.

When the stains seem set in stone... or granite, fiberglass, or whatever else the stained surface may be, there’s this Scrubbing Bubbles Foaming Bleach bathroom cleaner. It promises to remove the toughest soap scum and stains from mold and mildew too. To use, you spray on the foam, let it sit for a bit, then wipe it with a damp sponge or cloth before ringing. Left behind are gleaming, clean surfaces. It can be used on tile, tubs, showers, chrome, and more.
Customers rave about this formula saying it’s easy to use, priced well and produces amazing results. They also like that it clings to surfaces rather than running right off of them like some other products and note that it does wonders on even the grimiest surfaces.

If you don’t want to have to scrub the scum away (and who does?), there’s this scrub-free soap scum remover from Scrub Free. Made with OxiClean, the lemon-scented formula cuts through scum, stains and more and leaves your bathroom clean and smelling fresh. You just spray it on, wait a few minutes, then rinse it off. It’s non-abrasive too, so it won’t scratch or scuff your surfaces.
Customers say it’s effective and easy to use, and many use it to clean their entire bathroom and areas beyond as well (one reviewer claims it works well on white wall tires). Several note, however, that the smell can be strong and recommended ventilating the room well before using.
