The 10 Best Soap Scum Removers

For most tubs and showers, Scrubbing Bubbles Mega Shower Foamer is a quick fix: spray the thick foam, let it sit a few minutes, then wipe and rinse. The wide spray covers a whole wall fast, and the foam clings instead of running down to the drain. It also kills common bathroom germs when you follow the label. Crusty, years-old buildup may need a second round, and the aerosol scent is strong in a small room.

When spray alone won't budge a crusty film, Mr. Clean Magic Eraser Bath lets you scrub it off. Each wet pad pairs a scouring foam with a built-in Dawn soap, so there's no separate bottle to carry. It works well on glass doors, tile and faucets. That foam is a mild abrasive, though, so it can dull glossy acrylic, polished metal and soft plastic. Try a hidden spot first, and expect each pad to wear down fast.

Rejuvenate Soap Scum Remover is for people who would rather rinse than scrub. You spray it on, wait two or three minutes, and wash the film away with the shower head. The formula has no bleach and no grit, and Rejuvenate rates it safe on glass, tile, chrome and fiberglass. This gallon jug is a refill, so you'll need the brand's spray bottle or one of your own. A heavy, baked-on coat can take several passes.

Cloudy glass shower doors are the reason to buy Bring It On Cleaner. It's a thick cream with fine grit that you work in with a damp sponge, then rinse, and it lifts hard-water spots and soap film together. It's also handy on tile, faucets and the ring in a toilet. The maker warns that etched glass can't be fixed, and it isn't meant for marble, acrylic or soft plastic. The two-bottle pack costs a fair amount up front.

A bottle of Bar Keepers Friend Soft Cleanser goes after the chalky mineral layer that often hides under the greasy film. Its mild acid loosens lime and rust stains, and the creamy liquid clings to a tub wall where a loose powder would slide off. It also cleans stainless sinks and pots, so the bottle rarely sits unused. Wear gloves, rinse well, and never use it alongside bleach. The acid can etch marble and other natural stone.

CLR Calcium Lime & Rust is an acid spray for the white, crusty part of the mess: lime on shower doors, faucets and shower heads. Spray it, wait a minute or two, wipe, and rinse with plenty of water. The maker says it carries the Safer Choice label and has no bleach or ammonia. It does little to greasy, waxy film on its own, and it can etch marble, travertine and other natural stone.

Spray Method Daily Shower on wet walls and glass after each shower, then walk away, with no rinse or wipe. Used every day, it keeps a new film from building up, which takes far less work than scrubbing off a thick one later. It smells of ylang ylang, and the bottle is made from recycled plastic. It won't cut through a coat that's already heavy, so give the shower a deep clean before you start.

Lysol Power Bathroom Foamer comes in a trigger bottle rather than an aerosol, and it's cheap to keep on hand. The foam sanitizes in about half a minute and works on soap film, lime and mildew stains across glazed tile, tubs and fixtures, with no bleach in the mix. The label lists it as safe for septic systems. The trigger can sputter or feel stiff, and dense, older buildup still takes some scrubbing.

Wet & Forget Shower runs on a weekly routine: spray the walls, leave it 8 to 12 hours, then rinse with warm water. There's no scrubbing, bleach or ammonia, and Reviewed's shower cleaner roundup found it cleaned glass without much streaking. It's fine on acrylic, fiberglass and tile. The payoff builds over weeks rather than in one session, and some households find it leaves a dull film or barely dents older buildup.

Marble and travertine showers need a gentler hand, and StoneTech Soap Scum Remover is made for them. Acid cleaners etch these stones, while this foaming spray is built to lift film and water spots without harming natural stone, tile or grout. The maker lists it as free of volatile organic compounds, which helps in a small, closed bathroom. Expect to scrub, and results on heavy hard-water marks are mixed.
