How to Clean Your Shower Doors
First of all fill a bucket with hot water and using a sponge rub all over your shower doors to get them well moistened.
Then using a bathroom cleaner squirt a generous amount onto the abrasive side of the sponge and rub well over your entire shower screen. If you have a lot of water marks it will be more effective to using a stainless steel scourer.
Rinse your screen with plain warm water.
Now polish your screen with dry paper towels.
Obviously it is better to keep your shower doors in tip top condition in the first place. Wipe them dry after every use.
