Hold the can about 8 inches from your tub to coat the entire bathtub; it applies as a foamy, shaving cream consistency. Let it sit for a few minutes, then wipe it away with a clean, damp cloth. Scrubbing Bubbles also works well on showers, sinks, and other bathroom surfaces.

Rain-X 630035 Shower Door Cleaner

Rain-X Shower Door X-treme Clean is ideal for getting soap scum and hard water stains off the glass, including the most stubborn buildup. After applying it to your shower door or bathroom mirror, rub it in with a circular motion using gentle pressure. Then rinse it off with water or wipe it clean with a damp cloth.

Bring It On Cleaner Hard Water Stain Remover

If you're cleaning fiberglass, we recommend Bring It On! Cleaner. This effective solution is formulated with a patented detergent blend. If your fiberglass shower doors have hard water spots, residue streaks, or a buildup of soap scum, this cleaner is up for the task.

CLR PRO works on ceramic, porcelain, and natural stone tile surfaces. When soap scum, rust, hard water stains, or lime deposits build-up, spray on the foamy formula in an even coat. Let it sit for a few minutes (or longer for tougher stains), then rinse or wipe it clean to reveal stunning, sparkling tile. Even grout will look like new.

Removing stains is one thing, and preventing them is another. Clean Shower can do both. Whether soap scum has become a problem in your shower walls, door, vinyl curtain, or tub, this effective formula will clean and keep away soap scum. Spray it on once a day when your shower or bathtub is wet.
