Will my iron door knocker rust and bleed onto the door paint?
Iron needs to be cared for properly. There are a few products
you can coat your iron door knocker with the slow or halt the oxidation
process that causes iron to rust. In the spring you should check your
door knocker to make sure there is no winter damage. If rusting occurs,
sand the rusted area and follow instructions on one of the rust retardant
paints readily available on the market. Paint the door knocker again
with rust retardant paint to prevent future rusting.
If you care for your iron door knocker properly you will catch any
rusting in time to take care of it before it moves onto the paint on
the rest of your door!
