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.”

It can be used on most surfaces, though it’s not recommended for natural stone, marble or brass.

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.
