previously posted in r/cleaningtips but no solid answer yet, hope some of you can help me out as it’s my kitchen sink in South Germany:

I live in a tiny studio which is in an old building. I know the right side is for placing washed dishes and the gap (arrow pointing at it) is for water draining from the washed dishes. But it has a lot of crud/dirt sticking inside it and it spews out soapy water (second picture) when I do the dishes and stagnates there for a short time. The drainage of my sink is also slightly slow.

How do I clean it? Maybe cleaning it helps with a faster drainage flow…

  2. I usually squirt some detergent in there and pour boiling water after it.

  4. I put the drain clog crystals there and some warm water. it usually also kills any living thing trying to multiply.

  5. Usually the methods in the other comments work well. For a very through cleaning you could loosen the screw from above and then detach the drain under the grate (access it from below the sink). Keep a bucket below that drain while you detach it. There will be a bit of water in it.

    The exact way of detaching and reattaching it depends on the type of drain. Some are flexible, some are rigid pipes.

  6. take s screwdriver, unscrew the bolt, loosen the drainage below sink and clean with wet paper towel. screw bolt back in.
