Slate Fire Hearth Stain Removal

Updated February 21, 2017

A slate fireplace hearth provides a natural look with an earthy feel. The slate is a highly durable stone so the fireplace requires virtually no maintenance aside from a basic cleaning procedure, along with a stain removal procedure if necessary.

Why Choose a Slate Fireplace?

Slate is a natural, timeless stone that will work well with nearly any home design. When upgrading the home, the slate transitions well, providing an attractive, long-lasting fireplace that will last a lifetime without deteriorating in quality.

Regular Cleaning of Your Slate Fire Hearth

Regular cleaning can be done with a low-cost cleaner made from items you probably already have in the home. Mix 1 gallon water with 1/2 cup oxygen bleach and 1 squirt dish soap. Dip a nylon scrub brush into the mixture and scrub down the fireplace. This removes loose residue, smoke soot and most light stains. Remember to line the bottom of the fireplace to prevent cleaning solution from running onto the floor. Wipe down your slate fire hearth with a damp rag after cleaning.

Removing Stains From Your Slate Fireplace

Stains can be removed with a baking soda paste. Mix 3 parts baking soda to 1 part water in a bowl and stir to make a consistent paste. Spread a thick layer of the paste over the stain and let sit for about 30 minutes. Scrub with a nylon scrub brush and wipe down the slate with a damp rag. Repeat if needed.

Cleaning the Grout of Your Slate Fire Hearth

The grout surrounding the slate also requires cleaning. Moisten the grout with water, and scrub with a nylon scrub brush. To create a more abrasive texture that removes heavier build-up, sprinkle the brush with baking soda and scrub across the grout. Wipe down the grout with a damp cleaning rag when finished.
