If your shower screen looks foggy no matter how often you wipe it, you're not doing anything wrong. Much of South-East Queensland runs on moderately hard water, and that means every shower leaves behind a thin layer of mineral deposits. Add body oils and soap, and you get the cloudy film that won't budge with a normal spray-and-wipe.
Why it keeps coming back
Hard water carries dissolved calcium and magnesium. When the water dries on the glass, the minerals stay behind. A regular bathroom spray lifts the soap but not the mineral layer underneath — so it looks clean for a day, then the haze returns. To actually fix it you have to dissolve the minerals, not just wipe over them.
What actually shifts it
An acidic cleaner is what breaks down hard-water deposits. You don't need anything exotic — white vinegar does it, and so do the dedicated hard-water removers from the supermarket.
- Mix equal parts white vinegar and warm water in a spray bottle
- Spray the glass generously and leave it 5–10 minutes — don't rush this part
- Wipe with a non-scratch pad, working top to bottom
- Rinse with clean water and dry with a microfibre cloth or squeegee
For a stubborn, built-up screen you may need a second pass. A paste of bicarb soda and a little water, rubbed gently with a soft cloth, lifts the last of the film without scratching.
The 30-second habit that keeps it clear
“The cleanest shower screens we see aren't scrubbed the hardest — they're dried after every shower.”
Once the glass is clear, the trick is to stop the water drying on it. Keep a squeegee in the shower and give the glass a quick pull-down after each use. Thirty seconds while the water's still warm, and the minerals never get a chance to settle. It's the single biggest difference between a screen that stays clear and one you're re-cleaning every week.
When it's beyond a DIY fix
If the glass has been left for years, the deposits can etch into the surface and no amount of cleaning will fully clear it — at that point it's a glass-replacement conversation, not a cleaning one. Short of that, the vinegar method plus the daily squeegee handles almost everything.
