If you burn food while cooking in enamel cookware, this is not a reason to be upset: the problem can be solved without any particular difficulties.
An effective and safe method can be found.
This food product is a fairly popular cleaning agent that can cope with its task without damaging the surface.
To do this, you will need to dissolve about 400 grams of salt in water in a saucepan. You will need to wait at least three hours for the plaque to be removed.
Vinegar is no less effective in these matters. About 200 ml of liquid should be poured into a saucepan and left for two hours. After that, the burnt food residues will be removed without much effort.
The product should be brought to a gel state and locally applied to areas with burnt food. After 1-2 hours, the stains can be removed.
The product is used in exactly the same way as with citric acid. It is also very effective.
