Tips For Cleaning Cast Iron Fireplaces

Jul. 23, 2021

A cast iron fireplace will add a cozy, old-fashioned touch to the home-but only if the fireplace is in good shape. Here are some guidelines on how to clean cast iron fireplace elements and how to repair a rusty cast iron fireplace in case your fireplace needs heavier work.

You already know this, but it must be said: do not clean up when the fireplace is still hot, let alone clean up when there is a fire in the fireplace. The cleaning of the fireplace is often messy, so it is a good idea to cover the surrounding area with a plastic sheet.

Before cleaning the cast iron fireplace elements, you usually need to remove the ashes from the previous fire. Sprinkle the used coffee grounds on the dust before cleaning to prevent the dust from turning on your face.

Use a dustpan and brush to sweep out the ash. If there are ashes in the grate, you can knock them down to make it easier to clean up.

How to repair a cast iron fireplace

Maybe your cast iron fireplace is more than simple cleaning, it needs some repair work. You can find a professional, but there are many things you can do at home. Here is a quick guide for restoring the elements of a cast iron fireplace (if the fireplace is removable, you may find it easier to remove it from the wall first).

Protect yourself and the surrounding area

Strip paint with a commercial paint stripper

If you see an old cast iron fireplace that has not been used this century, it may be covered with layers of peeling paint. Use a commercial paint stripper and follow the instructions on the bottle.

Wipe with white spirit and a soft cloth

After you remove the paint, take a soft cloth and wipe the fireplace with white spirit to remove any residue.

Use steel wool to remove the rust

Clean any rust away with steel wool.

Finish by applying the iron paste

Follow the manufacturer's instructions and finish off with iron paste or grate polish.
