The glass shower doors attract soap scum and mineral deposits. These annoying residues can make an otherwise sparkling bathroom appear dirty. Consistent cleaning makes the job more accessible and prevents future buildup.
Samara Geller is an old database and research analyst at EWG Guide to Cleaners. She says the more people follow a routine to prevent mildew and mold from forming on surfaces, the less they’ll need to use a powerful acid-based cleaner. It would help if you had the right tools for the job.
We researched the best glass shower door cleaners by comparing their scents, ingredients, effectiveness, environmental impact, and value.
Best Overall
Rejuvenate Scum Remover No Scrub
It’s easy to use, powerful, and versatile. The hardworking cleaner can be used on many bathroom surfaces, including counters and sinks. The non-abrasive formulation can be used on showers that have stone tiles.
Mist it on ceramic tile, fiberglass, or natural stone. You can also mist it on plastic, chrome, and porcelain. No scrubbing is required. Spray it evenly on your shower, wait three minutes, and then wipe it off. If you have a shower head that can be removed, you may even wash it off. The glass will be crystal clear and shiny with no streaks.
Best Budget
CLR Multi-Use Rust, Calcium & Lime Remover
This budget-friendly industrial strength solution removes the most challenging spots like soap scum and calcium, lime, or hard water deposits.
Using this product on many surfaces, including porcelain, stainless steel, and ceramic tiles, is safe. You should avoid using this product on tile or stone countertops.
CLR doesn’t come in a spray form, so you must prepare a few things before starting. Mix the concentrate with warm water in equal amounts. You can apply the mixture to any surface with a sponge, cloth, or brush. CLR is a relatively safe product, as it does not contain ammonia or bleach and has been approved by the EPA Safer Choice Program.
Best for Hard Water
Bio-Clean Hardwater Stain Remover
Calcium in hard water can cause white spots on your shower glass. Bio-Clean’s industrial-strength cleaning solution is specifically formulated to remove stubborn mineral deposits.
It’s not an option that you can spray and walk away from. To make the process easier, you can buy a complete kit that includes all the tools needed: three brushes connected to an electric drill to do extra scrubbing and a silicone sealant for protecting glass against future staining.
The Formula remains the same, no matter your choice: it is highly abrasive and biodegradable. It is essential not to use it on soft surfaces or items prone to scratching, such as your faucet. You can test the abrasiveness of the product in a small area if you are unsure.
Best for Soap Scum
Clean-X Repel Glass & Surface Cleaner
This dual-purpose Clean-X cleaner makes removing soap scum, a buildup of soap, bathing products, and another soap residue easy. It dissolves soap scum, grime, and other contaminants and coats the glass in a protective coating that prevents future water stains.
It’s easy to use and does not require scrubbing. You need to wipe it thoroughly to get a streak-free finish. You can also use it on other surfaces, like chrome fixtures and wall tiles in the bathroom. While you clean your shower, you can also spruce your bathroom.
The only downside is that although the product should have a cherry smell, users say it is very faint.
Best for Mold & Mildew
RMR-86 Instant Mold and Mildew Stain Removal
RMR-86 Instant Formula is ideal for showers that have mold and mildew problems. The Formula also eliminates odors and associated stains. In just 15 seconds, it also prevents future mildew and mold growth.
The product can be used both inside and outside. It’s simple to use. Just spray, let it sit for several seconds, then wipe away the residue with a microfiber cloth or a rag. The Formula is infused with bleach, so you don’t need to scrub hard to remove even the most stubborn stains. Test the spray in a hidden area first to ensure it will not alter the color or finish. Wearing gloves or old clothes that you don’t care if the rush gets onto them is a good idea.
Best Water Repellent
Invisible Shield Glass & Surface Cleaner
Invisible Shield Glass & Surface Cleaner will not remove soap scum or other residues from glass shower doors. The cleaner works in one step, without mixing, waiting, or heavy-duty scrubbing. Spray the dual-action formulation on the dirty area and clean it with a microfiber towel. The result is a streak-free shine with water-repellent properties. The Formula, similar to car waxes, coats the glass with water-repellent properties that last a few weeks after cleaning.
The product is also very versatile. It’s the only product you’ll need for your bathroom, as it can be used on glass, porcelain, ceramic surfaces, metals, granites, and stones. The spray can be used to shine wall tiles, sinks, counters, appliances, and faucets.
