A small coup to repair the dent in the iron sheet

Use hot water for maintenance.

After the iron sheet is depressed, some hot water can be poured into the depression, heated to a certain extent, and pushed out by hand until the depressed part protrudes from its original position.

After the iron sheet is dented, it is unnecessary to repair it if the degree of dents is relatively small and does not affect the normal appearance and use. If the sag is relatively large, it is recommended to buy professional maintenance tools for maintenance.
