Powdered detergents are often poured into the washing machine tray.
It would seem that due to this the container should remain clean for a long time.
But the opposite effect is observed: the powder, which has not had time to dissolve, forms a film on the surfaces.
This is why the tray quickly becomes dirty and is difficult to clean.
However, there is one way that will allow you to return the device to perfect cleanliness without much effort.
But you will have to wait several hours for the effect.
First, this device must be carefully removed from the washing machine.
Then the tray needs to be placed in a basin or bucket and filled with vinegar solution.
The latter is prepared very simply: for every volume of nine percent vinegar there should be one volume of plain water.
The tray should lie in this liquid for 7-8 hours. Then the device should be washed with clean water, wiped well and returned to the washing machine.
It is most convenient to fill the tray late in the evening: in the morning it can be returned to its place, since it will be completely cleaned during the night.
