When you clean your shower tray, make sure you clean the drain too. You don’t need chemicals for this either: Just sprinkle three spoonfuls of baking powder into the drain and then pour in around half a cup of vinegar or diluted vinegar essence. When these products come into contact in the drain, a chemical reaction occurs including lots of fizzing and hissing. Leave the vinegar and natron to work for a few minutes and then rinse with hot water. Repeat the process if required.
To prevent the formation of unsightly stains on the shower tray and blocked drains: Wipe off water droplets after showering and then dry the shower with a towel. This will prevent the formation of limescale. The best way to protect the drain is to use a drain strainer. This will collect hairs and other residue that can quickly create an obstacle in the drain.
