frequently with warm water and soap and any burnt-on
substances removed.

cloth and lubricated with a little oil while still warm.

been left on the surface for a long time, or by aggressive
detergents containing phosphorus. After cleaning, rinse
and dry any remaining drops of water.

If this happens, the tap must be replaced.
