We have a fireplace with red bricks around it that never looks clean. If we wash with soap and water, it looks clean until it dries, and then it looks dusty on top of the brick. (The side of brick still looks clean.) Is there another method of cleaning, or some type of finish that could be put over bricks. — S.R., Fenton

It sounds like you're getting ready for fall with a nice warm fire in the fireplace. Cleaning the fireplace at the start of the season is a good idea for both the exterior and interior.

There are several ways to approach cleaning smoke from the brick and mortar surfaces. You probably already have everything you need at home. A homemade solution of one part laundry detergent, one part bleach and five parts water works well to remove smoke stains. Scrub the mixture into the brick face with a strong bristle brush. You also can use a mixture of one part ammonia with three parts water.

If the stain persists, try using a diluted (1:9) solution of trisodium phosphate. Do not use this on stone fireplaces as it may cause a stain. You can find TSP at any hardware or paint store.

Cleaning the mortar may take a little more effort. Use an old toothbrush or small wire brush to scrub a mixture of one part water with 10 parts muratic acid. Use a paper towel or rag to keep solution from running on the brick face. Let it stand for 15 minutes and then rinse thoroughly.

Now that the exterior is clean, it's time to look inside. Make certain the flue operates and that there is not any buildup of debris (bird nests) inside the chimney. I recommend using a creosote log the first time you build a fire. It will help to loosen any buildup of ash and soot that may have formed last season.
