Cast-iron metal is one of the strongest and most durable metal that is accessible for normal use. However, cast-iron can easily get rusty because iron easily reacts to oxygen and other chemicals in the atmosphere. That can be a bomber particularly for cast-iron antique sellers whose income depends on the presentation and quality of the products like cast-iron cat feeder, cast-iron stoves, cast-iron decoration, etc.

To remove the rusty area place a suitable amount of Colonel Brassy hard surface metal cleaner with a cloth and rub vigorously to the affected area. Then paint the cleaned area with a metal primer, followed by a rust-inhibiting paint.
