How Often to Clean Fireplace Bricks

When soot accumulates, it leaves the odor of smoke and unsightly black stains on bricks; ceramic tiles and grout; carpets, drapes and upholstery; and painted surfaces. It’s important to remove the soot often, because it can eventually cause permanent damage, especially to porous surfaces. The more often you use a fireplace, the more often you’ll need to schedule a time to clean. The sooner you clean away soot discoloration on fireplace bricks, the easier the job will be.

Before You Begin

There are several cleaning solutions that you can use to clean your fireplace. With each method, there are several steps you should take before you begin the actual cleaning, which will help remove soot and protect surfaces before you get down to the actual scrubbing.

Protect Your Floors

Grab a waterproof drop cloth to protect carpets and floors from spills and stains.

Clear Out Ashes and Debris

Start with a cold fireplace. Remove the andirons, grate, and all of the ashes and debris in the firebox. After disposing of the ashes safely, use a shop vacuum to gather up any small particles.

Vacuum and Dust the Fireplace Facade

Vacuum the hearth and fireplace surround to remove as much soot and dust as possible. Clear the mantle of any decorative items to prevent excessive dust from settling on them, as well.

Tips to Keep Your Fireplace Bricks Clean Longer

Spot clean any soot or grime with a paste of a few tablespoons of cream of tartar or baking soda and a small amount of water. Let it sit for about 5 minutes, then scrub lightly with a scrub brush and rinse. Use the right type of firewood that has a cleaner burn, producing less smoke and soot. This includes hardwoods such as oak, ash, and maple; and softwoods such as fir, spruce, and pine.

If the soot is not removed, repeat the steps. You can use up to one cup of TSP per gallon of hot water if needed.
