Clean drain screen easily
Actually, it was just a crazy idea that led to an attempt. But the result was amazing:
This morning I wanted to dispose of my shaving foam can, about 10 o'clock. To completely empty them, I emptied them completely in the kitchen sink and consciously sprayed the chrome strainer. When I returned from shopping around 2 pm, I rinsed off the shaving cream and lo and behold, the strainer shone like new.
Then I rubbed the edge thoroughly with a piece of kitchen paper - transition, strainer to the sink - and again the edge was completely clean, like new. Class and easy. Works with safety on all chrome or VA parts.
