The dirtiest appliance in the kitchen is the hood.
Some people forget that it also needs to be washed from time to time.
It is worth remembering that dirt and grease from the hood can get into the food.

But don’t be afraid and don’t use chemicals for cleaning; you can use table salt.
You should take a saucepan and pour 500 grams of salt into it, pour water there and heat it up, the solution should not boil.
You can remove the filter from the hood and boil it in a saucepan for ten minutes.
Or you can pour salt water into a basin and immerse it there if it is large in size.
If the filter does not clear, it is worth repeating the manipulation again or keeping it in the saline solution for longer.
