A prim bathroom is more than just nice living plants or bathroom accessories like luxurious linens. 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.

What We Like
  • No-scrub formula

  • Can be used on multiple surfaces

  • Ultra-clear, streak-free finish

What We Don't Like

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.

  • Can be used to clean entire bathroom

What We Don't Like
  • Doesn't come in a spray bottle

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 for your bathroom cleaning, too, including your tile, sink, toilets, drains, faucets, showerheads, countertops, and fixtures.

  • Biodegradable

If you're dealing with hard water, you might need to bring out the big guns—and by that, we mean Bio-Clean's stain-remover kit. You'll get a bottle of cleaning solution that takes on years of hard water stains and spots, not to mention mildew, mold, and rust.

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.

What Testers Say

"Once you’ve extracted the cleaner, it scrubs and spreads well—so, while you have to use more cleaner than you would with a spray, you still get a lot for your money. To get full use of this product, however, you need a drill to attach the brushes to. It takes the sweat out of the job and quickly rids your shower door of any cloudiness."—Stacey L. Nash, Product Tester
