If you are looking for a distressed or shabby chic look, merely remove any peeling paint and give the bed a thorough overall cleaning with a mild soap and water mixture. Use water sparingly and dry the metal as you go...rinse and dry each section immediately after washing.
Sometimes restoring an antique detracts from its value, but if the bed has heavy rust or significant dents, you may need to make repairs to the bed. A professional restorer can help with sandblasting or restructuring the bed. Some beds can also be converted to hold a queen mattress.
If you wish to paint the bed a pretty, fresh color, make sure there are no loose chips on the bed, then paint it with chalk paint or a spray paint made for metal. To protect the surface of your iron bed, whether painted or chippy, carefully apply a small amount of beeswax polish, buffing with a clean cotton rag as you go. You can remove excess wax with a dry rag.
Add soft, pretty sheets and a fluffy duvet, then pile on the pillows. Your bed is now ready for sweet dreams!
