Immerse the items in it and leave it for a few hours. This will make the stain softer and easier to remove afterwards!

With citric acid
Prepare a solution of 150 grams of citric acid and 1 liter of boiling water. Pour onto burners or griddles. Let soak for about an hour.

When the stains disappear, dry them gently with a cotton cloth.

With fine cleaning salt
The final solution is fine salt. Its abrasive action can remove stubborn stains and keep your burners and hobs looking like new!

In this case too, the procedure is always the same: Soak the ingredients in a pot with boiling water and three tablespoons of salt for at least an hour.

For stubborn dirt
In some cases, the above methods may be enough to remove all the dirt. However, if the stain is more resistant, even the most stubborn dirt must be removed. After soaking the panels, use a non-abrasive sponge and scrub vigorously until everything is removed. Then rinse and dry each part well, as remaining water can cause rust.
