How To Clean a Stone Fireplace?

A long winter of fires can leave your stone fireplace in need of a good cleaning. Smoke and soot can waft out and leave the stone dingy. You don’t need a pro to put the sparkle back in your natural stone fireplace.

Eliminating these accumulations on an ongoing basis—a relatively easy and inexpensive task—is the best way to maintain the beauty, efficiency, and safety of your hearth.

How To Clean a Stone Fireplace?

Use this procedure to protect living spaces surrounding your fireplace and pre-clean the firebox.

MATERIALS AND TOOLS

  • Drop cloths
  • Plastic tarp
  • Small shovel (15 to 30 inches long)
  • Metal container
  • Gloves
  • Dust mask
  • Plain water
  • Vacuum cleaner with brush attachment
  1. Allow your fireplace to cool for a minimum of 12 hours after extinguishing the last fire. Then lay drop cloths on the floor around the fireplace and a tarp over nearby furniture to protect them from cleaning fluids and airborne dust.
  2. After donning gloves and a dust mask, use a small shovel to scoop up the remaining ashes from the firebox. Place ashes in a metal container with a tight-fitting lid. Fill the container with plain cold water, close the lid, then store it outside the home away from other flammable materials until you’re ready to discard them.
  3. Use a vacuum cleaner with a brush attachment to siphon dust from the fireplace surround, moving from the top to the bottom. This will reduce accumulations on the stone surface and speed up your cleaning.

Follow fireplace preparation with your routine cleaning

During seasons of regular use, go through these steps for how to clean a stone fireplace on a weekly basis to remove light to moderate accumulations of soot, dirt, and grit that collect on the fireplace surround with each cozy night by the fire.

MATERIALS AND TOOLS 

  • Small bucket
  • Dish soap
  • Plain water
  • Wood stir stick
  • Gloves
  • Dust mask
  • Stiff-bristle scrub brush
  • Clean rags (2)
  1. In a small bucket, dilute a quarter-cup of dish soap in a quart of hot but not scalding water. (The emulsifying agents in soap are all you need to clean a fireplace that’s not heavily coated with soot). Stir with a wood stir stick until the soap has dissolved.
  2. After donning gloves and a dust mask, dunk a clean scrub brush into the soap solution, then scrub down the fireplace surround from top to bottom to loosen trapped dirt and grit in the stone and grout.
  3. Empty the bucket of soapy water and replace it with fresh cold water. Saturate a clean rag in the water, then make one to two passes over the fireplace surround with the wet rag to wipe away soap suds and any loosened dirt.
  4. Dab the fireplace surround dry with a dry rag, then let the fireplace surround air-dry completely before igniting your next fire.
