Quick answer
Cloudy shower glass is caused by limescale build-up and, worse, permanent etching from hard water and harsh cleaners. Prevent it by drying the glass after each shower with a squeegee, using gentle (non-acidic) cleaners, and choosing factory-coated easy-clean glass from the start. Light cloudiness can be cleaned off; deep etching is permanent, so prevention is everything.
Why glass goes cloudy in the first place
It helps to know there are two different problems wearing the same disguise. The first is limescale — mineral deposits left behind when water droplets dry on the glass. This sits on the surface and, caught early, wipes off. The second is etching, where minerals and harsh acidic cleaners actually eat microscopic pits into the glass surface. Etching is permanent — no cleaner brings it back, because the glass itself is damaged. Most “cloudy” screens are a mix of removable scale and a haze of etching underneath.
The good news for Plymouth: our water is relatively soft compared with much of England, so limescale is less aggressive here than in hard-water areas like the South East. That makes a clear screen genuinely achievable with a light routine — you’re not fighting the water as hard as some.
How to keep it crystal clear
None of this is hard work — it’s just a few habits and one good decision at fitting time.
- Squeegee after every shower — 20 seconds clears the droplets before they dry and deposit scale
- Skip harsh acidic cleaners — strong limescale removers can etch the glass; use a gentle bathroom spray
- Wipe down weekly — a soft cloth and mild cleaner, then buff dry
- Open a window or run the fan — drier air means less standing moisture on the glass
- Specify coated glass — a factory easy-clean coating makes water bead and roll off, so deposits struggle to form
That last point is the big one — we fit coated glass screens on walk-in showers precisely because it slashes the maintenance, as our are walk-in showers easy to clean page explains.
A squeegee after each shower and coated glass from day one is the whole secret to clear screens.
What if it’s already cloudy?
If your screen has gone hazy, try this before writing it off. Clean it with a mild limescale remover suitable for glass (test a corner first), working gently with a soft cloth or a non-scratch pad — never anything abrasive. A paste of bicarbonate of soda, or a half-and-half white vinegar solution left briefly then rinsed, lifts a lot of surface scale without the aggression of industrial acids. Rinse thoroughly, squeegee, and buff dry.
If it stays milky after a proper clean, you’re looking at etching, which is in the glass for good. At that point the only real fix is a new screen — and when you replace it, go for coated glass so the new one stays clear. If you’re already updating the bathroom, it’s the perfect moment; our bathroom renovation service can swap a tired, etched screen as part of a wider refresh.
Common questions
Does white vinegar damage shower glass?
Used briefly and rinsed well, a diluted vinegar solution is fine for occasional descaling. Don’t leave strong acid sitting on the glass for long periods, as repeated harsh treatment contributes to etching over time.
Is coated glass worth paying for?
Yes — the coating dramatically reduces how quickly scale forms, so the screen stays clear with far less effort. We recommend it on every new screen.
Can a cloudy screen be polished clear?
Surface scale can be cleaned off, but true etching can’t be polished out reliably. If a thorough clean doesn’t clear it, replacing the panel is the dependable fix.
A simple routine that actually keeps glass clear
You don’t need a cupboard of products — just a rhythm. After each shower, ten to twenty seconds with a squeegee pulls the water off before the minerals in it can dry and stick; that one habit does most of the work. Once a week, a quick going-over with a mild bathroom spray and a soft cloth, then a buff dry, deals with anything the squeegee misses. Run the extractor or crack the window while you shower so the glass isn’t sitting in warm, wet air for hours afterwards.
Do that and, with Plymouth’s relatively soft water, a coated screen can stay genuinely clear for years. Skip it and even soft-water scale slowly builds into the milky film people mistake for worn-out glass — when really it’s just deposits that were never wiped away.
The cleaning mistakes that cause the cloudiness
Ironically, the way many people try to fix a hazy screen is what ruins it for good. Two mistakes do the damage.
Reaching for the strongest cleaner
Heavy-duty limescale removers are acidic, and repeated use etches microscopic pits into the glass — the permanent haze no cleaner will lift. A gentle bathroom spray used regularly beats a harsh one used in desperation every time.
Scrubbing with the wrong pad
Abrasive scourers and gritty pastes leave fine scratches that scatter light and look just like cloudiness — and they’re just as permanent. Stick to a soft cloth or a non-scratch pad, and let the product do the work rather than the elbow grease.
Does the glass I choose at fitting really matter?
More than anything else you can do. A factory easy-clean coating bonds to the glass so water beads and rolls off instead of clinging and drying — it doesn’t wear off with normal cleaning and it turns a daily chore into an occasional wipe. It’s a small upgrade at fitting and the single best defence against cloudiness, which is why we fit coated glass as standard on new walk-in showers. If your current screen is past saving, swapping it for coated glass as part of a wider update is set out in our cost guide and FAQs.
