Limescale is one of the most stubborn marks on shower glass, especially in hard-water areas like Perth. The good news is you don’t need anything harsh to shift it. In fact, the one thing you should never use on shower glass is an abrasive such as sandpaper, steel wool or scouring powder. Here’s how to remove limescale safely and keep it from coming back.
What is limescale on a shower screen?
Limescale is the chalky white film left behind when hard water dries. Hard water carries dissolved minerals, mostly calcium and magnesium. Each time droplets evaporate on the glass, a little of that mineral stays behind, and over weeks it builds into a cloudy layer. Soap scum often bonds to it, which is why the haze can look grey or greasy as well as white.
Why you should never use abrasives on shower glass
Sandpaper, steel wool, scouring pads and gritty powders work by grinding. On glass, that grinding leaves fine scratches. Scratched glass looks permanently hazy, and the tiny grooves give minerals and soap scum more to cling to. Scratches can’t be cleaned away, so leave anything gritty in the shed.
How to remove limescale from shower glass
1. Water and a purpose-made sponge
For light to moderate build-up, start with plain water. Wet the glass and a sponge made for shower glass, such as our Shower Screen Cleaner Sponge, then wipe in firm, even strokes, keeping water between the sponge and the glass. Work in small sections. Heavy, long-term build-up can take a few passes.
2. A mild vinegar solution for stubborn spots
Mix equal parts white vinegar and warm water. Wipe it onto the marks with a soft cloth, leave it for a few minutes, then wipe again and rinse well with clean water. Vinegar is mildly acidic, which helps loosen mineral deposits. Keep it off natural stone and any surface where the manufacturer advises against acids, and never mix vinegar with bleach or other cleaners.
3. Rinse and dry
Rinse the glass with clean water and dry it with a squeegee or microfibre cloth. Drying is the step most people skip, and it’s what stops new marks forming straight away.
Check your glass first
Always patch-test any method on a small, hidden area first. Take extra care with coated, tinted, frosted or acrylic screens, and check the care instructions from your installer or the glass manufacturer.
How to stop limescale coming back
- Squeegee the glass after each shower.
- Give it a quick wipe once a week so marks don’t get a chance to build up.
- Run the exhaust fan or open a window so the bathroom dries faster.
- Deal with spots early, while they’re still a thin film.
Bottom line
Limescale on shower glass needs patience, not grit. Water, a purpose-made sponge, a little vinegar for stubborn spots and a quick dry afterwards will keep your screen clear. If you’d like an easy way to stay on top of it, the Shower Screen Cleaner Sponge cleans with just water: wet it, wipe and rinse.
