The best way to clean shower glass
You can try several products and methods to remove watermarks from glass. Before reaching for harsh cleaning chemicals, use white vinegar.

How to prevent watermarks and limescale
There’s nothing worse than cleaning your bathroom, only to find watermarks and limescale have reappeared the following day. These are some simple preventative measures you can incorporate into your home and daily routines.

Regular cleaning
A squeegee is one of the most practical and affordable items that can prevent watermarks and limescale from reappearing on your glass shower doors. Some feature a holder that sticks to your shower wall, making them easy to use every time you shower. After showering, squeegee all the moisture off the glass of your enclosure or screen to stop watermarks from appearing.
Good ventilation
Keep your bathroom well ventilated to help water evaporate quickly from your shower screen. Droplet marks are more likely to appear when water sits on the glass for long periods.
If your bathroom is poorly ventilated due to small windows, no extractor fan, or you’re having problems with damp, find out how to reduce bathroom condensation. If you have space for some decorative accessories, consider buying bathroom-friendly plants that absorb moisture.
Buy a water softener
Alternatively, you could buy a water softener machine if you live in an area with hard water. Hard water can cause damage to pipes and appliances and dry out your hair and skin, so this may be a worthwhile investment.
