View On Amazon View On Home Depot View On Walmart

Rejuvenate No Scrub Soap Scum Remover is our top pick for tackling soap scum and other buildup in your shower, because it's powerful, versatile, and exceptionally easy to use. But that’s not the only spot where you can use the hardworking cleaner—it works on other bathroom surfaces, including sinks and counters, too. You can even use the non-abrasive formula on showers with stone tile. 

Simply mist it onto ceramic tile, fiberglass, natural stone, plastic, chrome, porcelain, and glass, and watch it work its magic, quickly dissolving mineral buildup and water spots. There’s absolutely no scrubbing required. As the name suggests, you just spray it on your shower in an even layer, let it sit for three minutes, and wipe it away. (If you have a removable shower head, you can even rinse it off.) The result is crystal clear, shiny, and streak-free glass.

Best Budget

CLR Multi-Use Calcium, Lime & Rust Remover

View On Amazon View On Home Depot View On Walmart

It may be exceptionally budget-friendly, but this industrial-strength solution instantly removes some of the toughest spots, including soap scum, calcium, lime, and hard water deposits, to leave your shower or tub pristine. 

Still, it’s safe to use on a variety of surfaces, including plastic, ceramic tile, stainless steel, and porcelain. Avoid using it on stone counters or tile, but otherwise you can use this concentrate to clean most of your bathroom. 

Just note: CLR isn’t available in a spray formula, so there’s a few things to do before you actually get to work. The concentrate needs to be mixed with equal parts warm water. Once that is done, you can apply it to whatever surface you’re cleaning with a cloth, sponge, or brush. The entire process is relatively safe, since CLR doesn’t contain any ammonia, bleach, or phosphates and is approved by the EPA's Safer Choice program.

Best for Hard Water

Bio-Clean Hard Water Stain Remover

When you have hard water, your glass shower door is more susceptible to those pesky white spots—that’s because of all of the calcium in the water. Stock this industrial-strength cleaner from Bio-Clean, which is specially formulated to remove those stubborn mineral deposits. 

The powerful solution does require some elbow grease—it’s not a spray-and-walk-away option. But to make things a little easier, you can purchase an entire kit that comes with all the tools you need: three brushes, which can be attached to an electric drill for extra scrubbing, as well as a silicone sealant to protect glass from future staining. 

No matter which option you choose, the formula is the same: highly abrasive, yet biodegradable. That is why it’s important to avoid using it on soft surfaces and any items that scratch easily—like your faucet. If you’re not sure, take the time to do a spot test in an inconspicuous area to see whether the abrasiveness is too rough for your surface.

Best for Soap Scum

Clean-X Repel Glass & Surface Cleaner

View On Amazon View On Home Depot View On Walmart

Like hard water spots, soap scum—buildup from soap and other bathing products—can be very difficult to clean, but this dual-purpose cleaner from Clean-X makes the task a near-effortless chore. It quickly dissolves scum and other grime, and it works to coat the glass with a protective layer that helps prevent future water stains and buildup. 

The formula is spray-and-wipe, so it’s easy to apply and doesn’t require any scrubbing. (You just have to make sure to thoroughly wipe it down for a streak-free finish.) It’s also safe to use on other hard surfaces in the bathroom, like wall tile and chrome fixtures, for convenience. You can spruce up your entire bathroom while you're cleaning your shower door. 

If there’s any downside, it’s that the product is supposed to have a cherry scent, but users report that it’s very faint.

Best for Mold and Mildew

RMR-86 Instant Mold and Mildew Stain Remover

For showers with mold and mildew issues, try RMR-86’s instant formula. It also removes associated stains and odors simultaneously. It also helps prevent future mold and mildew growth—all in just 15 seconds. 

You can use the product both indoors and out, and it’s easy to use: Just spray and let it sit for a few seconds, and wipe it all away with a rag or microfiber cloth. There’s no need to scrub even stubborn stains heavily, thanks to the strong bleach-infused formula. You should always test the spray on an inconspicuous area to make sure that it won’t alter the finish or color. It’s also smart to wear protection, like gloves, and even old clothes you won’t mind ruining if some of the spray gets on them.

Best Water Repellent

Invisible Shield Glass & Surface Cleaner

View On Amazon View On Bed Bath & Beyond

Invisible Shield Glass & Surface Cleaner is no match for soap scum, hard water, rust, and other residues that commonly affect glass shower doors. It works in a single step—there’s no mixing, waiting, or heavy-duty scrubbing. Simply spray the dual-action formula onto the soiled area, then wipe clean with a microfiber cloth. The result is a streak-free shine, complete with water-repelling properties. Like car wax, the formula works hard to coat the glass with a water-repellent that works for about a week after your cleaning session. 

We love how versatile the product is, too. Besides a disinfectant, it’s basically the only product you need to keep your bathroom clean, since it’s approved for use on all glass, porcelain, ceramic, metal, granite, and stone. Use the spray to make wall tile, sinks, counters, appliances, and faucets shine.

Best Streak-Free

Rain-X Shower Door X-treme Clean

4.2

View On Amazon View On Walmart

This chemical cleaner is a gel-based product that comes in a standard squeeze bottle. The hardworking formula cleans in just three steps. Apply the cleaner to a damp cloth or directly onto the shower door. Then, scrub in a circular motion while applying light pressure. Finally, rinse and dry with a microfiber cloth for a streak-free finish. 

The formula is super thick, so you have to use a fair amount to coat your shower door, and budget some extra time for wiping it all away. It’s worth the effort, though: It’s specially designed to remove soap scum, dirt, hard water buildup, calcium deposits, lime stains, and rust stains.

Best Foam

OxiClean Foam-Tastic Foaming Bathroom Cleaner

View On Amazon View On 123office.com View On Home Depot

One of the biggest challenges when cleaning shower doors is that traditional sprays tend to drip on the vertical surface. But not this foaming formula. It sits right where you put it—even on vertical surfaces—so the stain-fighting bubbles make better contact with soap scum, hard water, calcium, and lime stains. What’s more, the formula is color-changing to take the guesswork out—it sprays on blue and turns to white when it’s time to wipe it off. No need for hard scrubbing. All you need to remove the foam (and the grime it takes off) is a wet cloth or sponge. It’s worth noting, however, that stubborn spots may require extra contact time or even multiple applications.

The lemon-scented product is highly versatile, too, because it can be used on other bathroom surfaces, like sinks, toilets, and countertops. It might not be the most cost-effective way to clean your bathroom, though. The 19-ounce bottles are on the smaller side, and the foam doesn’t seem to have as much mileage as sprays.
