A red brick fireplace can be a stunning focal point of any room. But stains from smoke and soot that accumulate on the red bricks in your fireplace can be tough to get rid of and can make your fireplace look dirty and shabby. It can take a lot of persistence and elbow grease to get rid of the smoke and soot. However, you can often accomplish this task using cleaning products you already have in your home.
Use a stiff-bristle brush to scour the red bricks in your fireplace with a scouring powder containing bleach. This should effectively remove the smoke stains. If it doesn't work, try using an alkali detergent or a commercial emulsifying agent. Always test a cleaning agent in an inconspicuous area of your fireplace before using it.
Use a stiff-bristle brush with white vinegar to scrub the red bricks in your fireplace. Soak the bristles of the scrub brush with white vinegar, and then scrub the surface of the bricks, concentrating on one small area at a time. Repeat this process until you have removed the soot stains from your fireplace.
Use a soft scrub brush and a solution of 1 part water to 1 part laundry bleach to clean an older red brick fireplace without damage. Pour the solution of water and laundry bleach into a spray bottle, and spray it over the areas of the fireplace you want to clean. Then scrub the bricks with a soft brush, and wash the area you scrubbed with water.
