Laundry flat irons of various ages (Leighton Buzzard LU7)

Unfortunately the shed roof leaked onto them all so they are very rusted. There are also curling irons. The irons range in age from the 1900’s to 1950’s- some were used with coal, others just flat irons heated on the stove or fire and others gas (?). They were my parents but I have no interest in this hobby and have no time to get them clean or rust free. They are extremely heavy. I just want them gone asap or they will be going in the skip that is being picked up next Wednesday morning.
