Clear glass is the whole point of a glass shower screen, and in much of the UK hard water makes that a constant battle. The good news is that a few seconds a day saves a lot of scrubbing later.
Why glass goes cloudy
That white haze is usually a mix of two things:
- Limescale: calcium and magnesium left behind when hard water dries. Much of England, especially the South East, London and East Anglia, has hard water.
- Soap scum: residue from soap, shower gel and shampoo that binds with minerals in the water.
Both build up fastest where water sits and dries slowly, such as the bottom edge of the glass, around hinges and inside frames and tracks.
The daily habit: squeegee
The single most effective thing you can do is squeegee the glass straight after showering, while it is still wet.
- Start at the top and pull the squeegee down in overlapping strokes.
- Wipe the blade on a towel every few strokes.
- Finish along the bottom edge and around the seals.
It takes under a minute. Leaving the door open or running the extractor fan afterwards helps everything dry faster.
The weekly clean
- Use warm water with a small amount of washing-up liquid, or a bathroom cleaner labelled safe for glass.
- Wipe with a soft microfibre cloth or non-scratch sponge.
- Rinse with clean water and dry with a squeegee or a second dry microfibre cloth.
- Wipe the seals, hinges and wall channel too, since that is where scum and mould tend to start.
Dealing with limescale
For visible build-up:
- Mix a descaler made for glass according to the label, or use a solution of white vinegar and warm water (around one part vinegar to one or two parts water).
- Apply with a cloth or spray, leave for a few minutes, then wipe with a soft cloth.
- Rinse thoroughly with clean water and dry.
Be careful with acidic cleaners, including vinegar, around natural stone such as marble, limestone and travertine, and around some metal finishes such as brushed brass or matt black. Acid can etch stone and dull finishes. Protect them, or use a product the manufacturer approves.
What to avoid
- Scouring pads, wire wool and abrasive powders or creams. They scratch glass and can strip easy-clean coatings.
- Razor blades or scrapers, unless the glass manufacturer specifically says they are safe on that glass.
- Strong solvents and bleach on seals and hardware, which can perish rubber and damage finishes.
- Leaving any cleaner to dry on the glass.
Easy-clean coatings
Many screens come with a factory-applied coating that makes water bead and run off. To keep it working:
- Use only mild, non-abrasive cleaners.
- Check which side is coated (often the inside) and follow the manufacturer’s care guide.
- Some coatings can be topped up with a product recommended by the manufacturer. Aftermarket glass protection treatments are also available if your glass is uncoated.
Seals and mould
Black spots on seals are usually mould. Wipe seals weekly and dry them. If mould has got into the rubber, replacement seals are usually inexpensive and easy to fit, and they make a frameless screen look new again.
A routine that works
| When | What | Time |
|---|---|---|
| After every shower | Squeegee, door open, fan on | 1 minute |
| Weekly | Mild cleaner, microfibre, rinse and dry | 5 minutes |
| Monthly or as needed | Descale build-up, clean seals and hardware | 15 minutes |

Frequently asked questions
What is the best way to clean a glass shower screen?
Squeegee the glass after every shower, wipe it weekly with warm water and a little washing-up liquid or a mild glass-safe cleaner on a microfibre cloth, then rinse and dry.
How do you remove limescale from shower glass?
Use a descaler made for glass, or white vinegar mixed with warm water (about one part vinegar to one or two parts water). Leave it for a few minutes, wipe with a soft cloth, rinse well and dry. Keep acidic cleaners away from natural stone and some metal finishes.
Should shower doors be left open after a shower?
Yes. Leaving the door open or running the extractor fan helps the glass and seals dry faster, which means less limescale and mould.
What should you not use on a glass shower screen?
Avoid scouring pads, wire wool, abrasive powders or creams, and razor blades unless the manufacturer says they are safe. They scratch glass and can strip easy-clean coatings. Avoid bleach and strong solvents on seals and hardware.
