4 tips for preventing a blocked sink

A sink can easily get blocked with daily use. The tips below will help you prevent a blocked (kitchen) sink.

1. Do not leave food remains in the kitchen sink
Wipe off dirty dishes with a paper towel above the bin and remove most of the remaining food. Then wash the plates in the sink with water and a washing up brush or in the dishwasher. And maybe put an extra filter above the sink to prevent food remains from getting into the drain.

This rinses the sink and the hot water carries away the grime. And this does not damage the drain in any way.

3. Use soda regularly to rinse the drain
Soda is stronger than water so it removes more grime.

4. Never throw frying oil or gravy in the sink
It does sound like an easy solution to just throw the oil you used for frying in the sink. But frying oil, just like gravy, coagulates when it cools. It then forms clumps that also block other food remains, etc. causing even more build up.
