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.
It may take a bit of elbow grease for especially stubborn scum and water stains, but it’s worth it for dream clean glass.
For ease of use and effectiveness, these Magic Eraser cleaning pads from Mr. Clean get top marks for fiberglass tubs and showers. They work on plenty of other surfaces as well, including glass and counters.
They’re bigger than traditional Magic Erasers and are formulated just for bathrooms. They contain a foaming cleaning agent, which you activate by adding water, so each one is a complete cleaning tool. They also contain Febreze Freshness, so they’ll leave your bathroom smelling nice too.
Hard water can be hard on showers, but this cleaner says bring on the scum. Aptly named Bring It On, this cleaner is ready to take on the scummiest scum and stains too. The key ingredient is oxygen bleach, which is non-toxic, and it can be used on most surfaces, including tile, stone, and metal. The smell is described as minty and refreshing. It works amazingly well, and a little goes a long way.
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 the smell can be a bit overpowering, the clean it produces is amazing.
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.
It’s easy to use and cuts down on cleaning significantly when you use it regularly. Plus, the smell is pleasant 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.
This formula is easy to use, priced well, and produces amazing results. It clings to surfaces rather than running right off of them like some other products and 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.
It's effective and easy to use, and many use it to clean their entire bathroom and areas beyond as well (it works well on whitewall tires). The smell, however, can be strong and we recommend ventilating the room well before using it.
