I live in Baltimore City, Maryland in a 30 yr old townhome development with 133 homes. When this development was built in 1987, the builder used wrought iron railings inserted into the concrete stairs/landings. Overtime, these railing posts have begun to release rust, at the base of the posts, on the concrete. The entire development has this rust problem and several homeowners have tried different methods to remedy this problem without any luck.
Do you have any suggestion for a sure fix without having to replace the railings?
