Chimney bricks are able to withstand high temperatures without much maintenance. After years of fire, the bricks can get dirty with the soot of charcoal from burned firewood. Too much soot can cause too much smoke in the chimney, which produces carbon monoxide dangerous for poisoning. Clean the bricks before starting each season.
- Mix 1 ounce (30 ml) of liquid soap with plenty of table salt in a bucket. Mix it with a little water to make a thick paste.
- Spread the pasta on the bricks of the fireplace and let it sit and dry for at least 10 minutes.
- Rub the paste on the bricks with a hard chimney brush.
- Rinse the bricks with a little warm water to remove the salt residue and prevent salt marks from forming on the bricks.
