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.
