How To Clean Antique Cast Iron Hardware
Cast iron hardware brings a rustic, and long lasting aesthetic to an interior that can be appreciated in many different design disciplines.
Cast iron is a finish that continues to age with time, so it’s a finish that does need to be adequately maintained to achieve the most desirable finish in your interior.
Whether it’s cast iron hooks, shelf brackets or door knobs, we explore how to clean antique cast iron hardware to help you retain and appreciate its finish as it ages.
Can Rusted Cast Iron Be Cleaned?
Yes, rusted cast iron can easily be cleaned, helping to bring the finish back to life. One method is to scrub the cast iron with a stiff brush or wire wool with hot water, then dry it thoroughly and coat it with oil to prevent further rust.
Another method is to cover the rust with kosher salt, cut a lemon and rub the rust off with the lemon. Avoid using soap here, as it can strip the pan of its natural oils and lead to rust.
How To Clean Antique Cast Iron Hardware
It’s quite common over time for the glossy, black finish on cast iron to wear away, allowing the surface to develop rust spots. Whilst this can look unsightly, regularly cleaning the cast iron correctly will keep the finish looking good, and retain the integrity of the finish.
Generally just cleaning with water is not the answer, as water and moisture is the very thing that will encourage more rust on the item.
There are a number of different methods to clean cast iron hardware, depending on the finish and severity of the rust. Here are some of the best steps you can take to cleaning antique cast iron hardware;
-
Start by washing the cast iron with a small amount of warm, soapy water and a stiff brush or wire wool. Be sure to scrub all surfaces, including the inside of the product and any ornate details, if any. This will help to loosen any rust spots that have been picked up with age.
-
Rinse the cast iron thoroughly with warm water and dry it immediately with a towel. This part is important as any moisture left behind will create an opportunity for rust to quickly reform.
-
If there is still rust or other tough stains, you can make a paste of equal parts water and baking soda and apply it to the stains. Let it sit for a few minutes, then scrub with a stiff brush and rinse with warm water.
-
If the cast iron still has stains or rust, you can try using a solution of equal parts water and white vinegar. Soak the cast iron in the solution for about an hour, then scrub with a stiff brush and rinse with warm water and dry thoroughly.
-
Finally, coat the cast iron with a thin layer of vegetable oil and heat it on the stove until the oil starts to smoke. Once cool, wipe off any excess oil and it is ready to use. Alternatively, coating it in a good lacquer will help to seal the cast iron finish.
If you have a cast iron product that is very old, or valuable, we’d always recommend seeking advice from an expert before you attempt to clean it.
It’s important to regularly maintain and clean your cast iron hardware as appropriate to help retain its finish, and enjoy its rustic charm for many years to come.
