Washing powder in the sink

In the kitchen, I have a white plastic sink that is quickly unsightly by all sorts of dirt.

If necessary, I take 1/2 cup of washing powder and run some hot water in the sink, a few hours act, afterwards the pelvis looks like NEW! Make sure that it is washing powder that is suitable up to 90 degrees, only this is how it works. Liquid or mild detergents do not work. Can you do the way with other white plastic things, z. B. Thermos.
