How to clean a fireplace with stone setting

A fireplace with stone surrounds can make a room feel cozy and comfortable, but inevitably the stones will begin to darken by the soot and smoke. The task of cleaning the moderately rough stones that around your fireplace requires some potent chemicals to restore the color, so please goggles and gloves to avoid injury and splashes. Put old towels on the floor and near furniture to protect them from dripping.


  1. Mix the commercial soot liquid stain remover with water according to the manufacturer’s instructions. Generally, 1/4 cup of disodium phosphate cleaner is used in 1 gallon of water. Locate the bucket nearby, so that you can reach it easily and with a minimum drip.
  2. Soak a sponge in the solution, then press it against the dirty area of ​​the stone fireplace with medium roughness. Choose a raised area and move down so that the dirt does not run into clean sections. Allows the humidity to take effect for a few minutes so that the solution can break down the soot and dirt.
  3. Rub a small area using the brush. Clean with small circular movements and close, and press strongly so that the bristles penetrate the porous stone.
  4. Give a clean, damp sponge to the area. Check the area to determine if the medium roughness stone is clean. Repeat steps 3 and 4 if stains persist.
  5. Clean the entire stone front of the fireplace, using a clean damp sponge to remove any residue of soot and grime. Allow the stones to dry completely by themselves.

Tips & Warnings:

  • If you are concerned that the cleaning solution will penetrate through the towels, consider putting a protective plastic sheet and sealing the edges with painter’s tape. Instead of a commercial soot cleaner, you can try a homemade blend consisting of one gallon of hot water, one ounce of chlorine or oxygenated bleach and one ounce of dishwashing liquid detergent.
  • Do not let the cleaning solution come in contact with your skin, your eyes or your mouth.
  • Ventilate the area before starting.
  • If your chimney is old and the stone is crumbling, call an expert cleaning chimneys to clean and repair.
