Bricks are porous, and their tiny holes serve as great storage spots for black soot. Soot is an amorphous carbon material that is a product of the burning process. Because soot is a fine material, it can easily work into the bricks’ pores, and it is difficult to simply wipe away with a cloth. Instead, special cleaning instructions should be followed to remove the soot without damaging the bricks.

Homemade Fireplace Brick Cleaning Solutions


Here are some of our go-to DIY cleaning methods for your brick fireplace:


Dishwashing Liquid Soap and Baking Soda


In a bowl, combine a half-cup of baking soda with three tablespoons of liquid dish soap. Allow this mixture to sit over the soot-stained area for 10 minutes. Then scrub it thoroughly, and rinse it with clean water.


White Vinegar


If a large portion of your brick fireplace is covered by soot, using vinegar and water is a smart option. Combine equal parts of white vinegar and water in a spray bottle. Cover the brick with the vinegar and water solution until it is wet. Then, use a scrub brush and your own labor to scrub away the soot. After scrubbing, rinse the fireplace bricks with clean water and allow the surface to air dry.


Cream Of Tartar


If you only need to clean a small area of soot from a brick fireplace, cream of tartar is a great option. Add two tablespoons of cream of tartar with a small amount of water to form a thick paste. After the paste sits on the surface for 10 minutes, rinse it off when clean water.
