The quickest answer to how to clean shower glass: wet the glass, spray it generously with a mild glass cleaner or a vinegar and water mix, wipe it with a clean microfibre cloth, then squeegee it dry from the top down. Do that weekly and squeegee after every shower, and most screens stay clear. Soap scum, hard water stains and the cloudy damage people call glass cancer each need a slightly different approach, and a few popular tricks do more harm than good. This guide is part of our wider guide to shower screens in a Melbourne bathroom renovation, written by glaziers who supply, fit and replace shower glass.
How to clean shower glass: the weekly method
Most shower screens are toughened safety glass, and some framed screens use laminated glass. The glass makers’ advice is consistent across both. Viridian’s Glass Cleaning Guide says to spray the glass generously with a glass cleaning solution or a vinegar-based product, wipe it with a clean, lint-free cloth, and stop just before it dries fully so it does not streak. Its home-made mix is one part vinegar to ten parts water. EnduroShield, the easy-clean coating maker, recommends cleaning treated shower glass each week with a damp microfibre cloth and a mild detergent. Put together, the weekly routine is:
- Rinse. Run the shower over the glass or wipe it with warm water to loosen the film and wash off grit.
- Spray generously. Use a mild glass cleaner, a little dishwashing detergent in water, or the vinegar mix. A wet surface lifts grime and stops your cloth dragging it around.
- Wipe top to bottom. Work in overlapping passes with a soft microfibre cloth or non-scratch sponge. A soft toothbrush and the same solution reach the corners and the edges along the seals.
- Squeegee and buff. Pull a rubber squeegee down the glass, then buff the edges with a dry microfibre cloth.
Replace cloths and sponges once they wear out. Guardian Glass’s care guide for its shower glass warns that a dirty cloth can scratch the surface by rubbing trapped grit across it.
How to remove soap scum from shower glass
Soap scum is the greasy, grey-white film that builds up where the spray hits. It is a mix of soap, body oils, shampoo and the minerals in your water. As our article on why white staining forms on shower glass explains, mineral deposits give soap scum something to cling to, so the two usually build up together.
To get soap scum off shower glass, start with the weekly method but let the solution sit for a few minutes before you wipe, so it can soften the film. Detergent cuts the oily part. For scum that has hardened with minerals, the vinegar mix does the work, followed by a thorough rinse with clean water. Work in sections on a big screen so the solution does not dry before you reach it. If the film comes back within days, the fix is not a stronger product. It is drying the glass after each shower, which we cover below.
For a screen that has been neglected for months, the trick is lubrication, not pressure. Rinse the glass with fresh water first to wash off loose grit. Spray the cleaner on generously so the surface stays wet and soapy, which helps lift the muck and stops the grit you are removing from scratching the glass. Work over the whole panel with a soft, non-scratch pad in small circles, top to bottom, with light, even pressure. Then squeegee across from one side, top to bottom, and finish with a clean microfibre cloth.
Hard water stains: how to clean glass shower doors with hard water stains
Hard water stains are the chalky white spots left when water dries on the glass and leaves its calcium and magnesium behind. They need a mild acid. EnduroShield’s advice for mineral build-up is a solution of one part white vinegar to four parts water, sprayed on and wiped off. Guardian Glass’s care guide gives a handy test: spots that wipe off with soap and water come from soft water, spots that need vinegar come from hard water, and spots that vinegar will not shift point to high-silica water.
What about shop-bought descalers? Read the label first. CLR’s own directions for its Calcium, Lime and Rust Remover say to mix it with equal parts warm water, test a small hidden area, leave it no longer than two minutes and rinse thoroughly with cold water, and to keep it off aluminium and painted, coated or sealed surfaces. So keep it off aluminium frames and coated glass. Viridian also says not to use cleaning agents containing hydrofluoric or phosphoric acid on glass, so check the ingredients on any stain remover. Never mix a descaler with another product.
Windex or vinegar? For routine cleaning, either is fine. AGC, the glass maker, lists both vinegar and Windex among the non-abrasive household cleaners suitable for its coated shower glass. For mineral spots, the acid in vinegar is what makes the difference.
Glass cancer: what it is and whether you can remove it
Glass cancer is not a technical term. Starts at 60, writing about the problem in 2026, describes it as hard water staining, soap scum and mineral deposits and, if neglected long enough, actual etching of the glass. Glass makers call that last stage corrosion. AGC explains that glass can age through surface corrosion caused by exposure to water, heat and high humidity, leaving it looking dull and dirty, and EnduroShield says unprotected glass will begin to permanently etch from water-borne minerals.
The useful test from the same Starts at 60 article: if the screen turns clear when wet but goes cloudy again when it dries, you have build-up, and the vinegar method above will help. If it stays dull and milky whatever you do, the surface is etched. Etching cannot be cleaned off, and scrubbing harder with abrasives only adds scratches. The fix is new glass. Our shower screen repairs team can often replace a single panel, made to match the existing screen.
Shower glass coating: EnduroShield
The easiest screen to clean is one that stops mineral and soap build-up bonding to the glass in the first place. That is what a shower glass coating does. EnduroShield easy-clean glass coating is a treatment Economy Glass applies to glass. It is not a never-clean product, it just makes cleaning much easier.
EnduroShield’s care advice for treated shower glass is a weekly wipe with a damp microfibre cloth and mild detergent. It says a squeegee is not required after each shower unless you are in a hard water area. It also says to avoid rough, gritty, highly acidic, alkaline or abrasive cleaners, including cerium oxide, on the coating. EnduroShield applicators can coat existing glass as well as new glass, so ask us whether your screen is a good candidate before you plan a replacement.
How to keep shower glass clean every day
Knowing how to clean shower glass matters less once you stop the build-up. The single habit that matters most is also the quickest. CHOICE suggests keeping a small squeegee in the shower and wiping the screen after showering, because it helps stop soap scum from setting and saves extra scrubbing later. Our guide to preventing white staining makes the same point: keeping the glass dry is the most effective prevention there is.
Leave the bathroom door or window open, or run the exhaust fan, so the room dries out after a shower. Keep an eye on the silicone too. Mould on silicone is a common problem in wet areas, which is why our article on neutral cure and sanitary silicone recommends mould-resistant sealants on new glass installations. Even those need regular cleaning. Economy Glass does not re-silicone old screens, so if the seals have failed, a replacement screen is the lasting fix.
What not to use on shower glass
Toughened glass scratches more easily than people expect. Viridian explains that fine glass particles can fuse to the surface of heat-treated glass during manufacturing, and that a blade can drag them across the surface and scratch it permanently. Viridian’s guide says not to use razor blades, metal tools, scouring pads, steel wool, abrasive or powder-based cleaners, or cleaning agents containing hydrofluoric or phosphoric acid. Some older cleaning tips, including ones once published on this page, suggested fine steel wool pads. Do not use them on your shower glass.
Bleach needs special care. The Better Health Channel says not to mix bleach with ammonia, acids or other cleaners because it can release hazardous chlorine or chloramine fumes, and CHOICE warns specifically against mixing bleach and vinegar. Never combine bleach with vinegar, descalers or any acidic cleaner, and rinse well between products. Skip the furniture oil some old tips recommend as well: none of the glass makers’ care guides we checked suggests it.
