One of the unfortunate
parts about having a fire in your brick fireplace is that
smoke can stain and discolor the brick above the fireplace.
You can remove this stain from your fireplace.
Start at the bottom,
wetting bricks even if they aren't stained. When water drips
down the wall, it will help prevent the running off water
from staining those bricks too.
Use a special abrasive
brick cleaner following the instructions on the package. You
usually will need to continue to rinse until the water runoff
is clear.
You may want to
wear gloves when you clean off the smoke stains from your
fireplace to protect your hands.
