Glass shower doors can accumulate soap scum, limescale, hard water stains, dirt, grime, and other buildup. These residues can make an otherwise clean bathroom look a little drab. Needless to say, you'll want to have a cleaning solution on hand to tackle the issue. We recommend something formulated specifically for shower doors—regular glass cleaners can work, but they may not dissolve shower residues as well. We researched standout formulas for all types of shower doors and every cleaning concern.
Here are the best cleaners for glass shower doors.
Best Overall: Rejuvenate No Scrub Soap Scum Remover
Non-toxic and non-abrasive
Can be used on multiple surfaces
Ultra-clear, streak-free finish
Works best on inside of shower door with access to shower head for rinsing
If your shower is covered in soap scum and other residues, Rejuvenate No Scrub is at your service. This award-winning product is non-toxic and non-abrasive. When you spray it on, it immediately gets to work, dissolving filmy mineral buildup and water spots on glass.
As the name suggests, you don't have to do any scrubbing. Just point it at your shower door, pump the nozzle to coat it in an even layer, then wipe it away or rinse it off and marvel at the crystal-clear glass with a streak-free shine. This cleaner can also be used on acrylic, plexiglass, ceramic tile, grout, natural stone, chrome, stainless steel, and plastic, so it's safe for pretty much every surface in your shower.
Best Budget: CLR Multi-Use Calcium, Lime & Rust Remover
Effectively removes residues from glass

Doesn't come in a spray bottle
This 28-ounce jug of CLR only costs a few dollars, but it'll make your shower door look like new. The industrial-strength solution is formulated to break down soap scum, calcium buildup, hard water deposits, and limescale from glass and fiberglass.
It works quickly to address discoloration and anything else getting in the way of an immaculately clean shower door. You can use CLR all over your bathroom, too, including your tile, sink, toilets, drains, faucets, showerheads, countertops, and fixtures.
Best for Hard Water: Bio-Clean Hard Water Stain Remover

While the formula works like an industrial-strength product, we appreciate that it's biodegradable. You'll also get a set of drill brushes, which you can connect to an electric drill for deeper cleaning, plus a silicone sealant to protect your shower door from more stains for up to two years.
