If you have an iron that is too old  , maintenance can always be useful,  but you cannot expect miracles, because  an iron that has had its time cannot have much left to give  . All that remains is to buy a new one. Nowadays there are various models on the market, both traditional and modern, there are even vertical irons that allow you to remedy small wrinkles in a few minutes without having to take out the ironing board.

Those who do very little ironing  can settle for a classic iron  , while those with a large family can buy an iron suitable for ironing large quantities of laundry, for example a professional one with a boiler. The latter requires more attention.
