Fireplace walls often have a film of soot and other debris that accumulate over time, so if you want to keep your home clean, you will need to get some supplies and eliminate the dirt. Soot can gather due to the fact that there may be smoke coming out from the fireplace or if you fail to open the flue before you start the fire. Most of the time, you cannot prevent the accumulation of soot, so cleaning should be performed regularly.


Step 1 – Prepare the Area

Cleaning your brick fireplace walls may be messy, so protect your floors and neighboring areas using a drop cloth or old newspapers. A drop cloth is more practical, as it will absorb the water that may be dripping while you clean the walls. Get your cleaning supplies and protective mask, gloves and eyewear.

Step 2 – Remove Dust

Get a dust brush and remove the dust that may be deposited on the brick walls. If you fail to remove dust and apply water, the dust will mix with water and it will be more difficult to remove.

Step 3 -- Wet the Wall

Fill a plastic bucket with lukewarm water (the water may be colder or warmer, as long as your hands are comfortable with the temperature). Apply water to the fireplace walls using a sponge or a piece of cloth. Start from the uppermost part and work your way downwards.

Step 4 – Apply Bathroom Cleaner

Get a bathroom cleaner spay and apply it over the entire surface. Make sure you cover the entire wall with cleaning solution. Let the solution work for up to 3 minutes before you move on to the next step.

Step 5 – Scrub the Walls

Use a scrub brush and start cleaning the brick fireplace walls. Start from the top part and work your way down. If you start from the bottom part, you may have dirty water dripping from the top over the bottom areas that are already clean. Cleaning the joints and mortar as well.

Foam will form once you start scrubbing and it will have the color of the soot.

Step 6 – Clean the Brick Joints

The brick joints may gather more dirt and may be difficult to remove with a scrub brush. If you see that there is dirt remaining in the brick joints, use an old toothbrush to clean this area. You may apply additional bathroom cleaner and scrub until you see that all the dirt is gone.

Step 7 -- Rinse

Use a clean sponge dipped in clean water to get rid of the foam from the fireplace walls. Get a bucket of clean water and dip the sponge as needed. You may need to change the water several times.

Step 8 – Remove the Newspapers

Clean the working area and remove the drop cloth or old newspapers. If your floor is wet, wipe it with a mop.
