If the water in your area is hard, chances are that your shower screen, taps and other bathroom fittings will soon be covered with the hard, off-white, chalky type deposit known as limescale. Maintaining and cleaning limescale areas is the best way to stay on top of the build-up. There are many limescale cleaners on the market that are quite expensive but, to save money, you can make your own mixture to clean your shower screen and other areas of the shower or bathroom.
Fill a bucket with warm water, and use a sponge to wipe down the screen. It's best to dampen the screen before applying any cleaning solution or mixture.
Mix a cup of vinegar with a cup of water in a separate bowl or bucket. Apply this mixture generously to the shower screen using the sponge. Let the solution to sit for 10 minutes so that it has enough time to penetrate the limescale.
Rinse the solution from the screen using the sponge soaked in water. Continue to rinse the solution until each area has been thoroughly rinsed and cleaned. If needed, repeat this process for stubborn areas.
