Safety glasses 

If you’re planning on cleaning your brick fireplace, you should wear safety glasses and rubber gloves. This will protect your hands and floors from any chemicals and grease. Safety goggles and rubber gloves will also protect your eyes. Once you’ve chosen the right tools, you can begin cleaning the fireplace. 

First, wet the bricks thoroughly. This is especially important if you’re using an acidic cleaning solution on porous bricks. Otherwise, the cleaner could eat away the brick from the inside. When cleaning bricks, you should work in small circular motions, starting at the outer edges and working inward. Then, rinse everything thoroughly with clean water. 

Rubber gloves 

If you have a brick fireplace, you should wear rubber gloves and safety glasses while cleaning it. This will help you avoid any damage to the skin. It is also important to clean it with a mild solution before using a harsher one. The chemicals found in the cleaning solutions can harm your skin if you do not use gloves. 

First, you should wet the brick thoroughly. This will help prevent the cleaning solution from penetrating into the brick. This is especially important if you’re using an acidic cleaner. Acidic cleaners can eat away at porous brick from the inside. Once you’ve wetted the bricks, use rubber gloves to scrub the brick with the cleaning solution. 

Muriatic acid 

Muriatic acid is a chemical that can be used to clean brick fireplaces. However, it is dangerous and requires special techniques and safety gear to be effective. For this reason, you should wear full safety gear and a respirator to protect yourself from the acid’s fumes. You should also avoid using the acid inside your home. 

Muriatic acid is a very harsh chemical, and should not be used haphazardly. It is best to follow the directions on the container. You should also use a buffered product rather than the unbuffered variety as this can lead to stains on the brick. Another safer alternative to muriatic acid is phosphoric acid, which is widely available at home improvement stores and hardware stores. 


You can clean your brick fireplace by using a mixture of borax and water. This solution is odorless and alkaline. Borax is a compound that increases the cleaning power of detergents. It also contains minerals and dish soap and can help clean your brick. After applying it to the brick surface, scrub it with a sponge or a bristle brush. 

Borax can also be used to clean stubborn stains. It’s a good idea to wear protective clothing and a mask to avoid skin contact. The borax solution works well on stains that have stuck to white bricks. 

High-gloss sealant 

If you are thinking of cleaning your brick fireplace, the best way to start is by soaking it in water. This will help remove any grime buildup. Rinse the bricks thoroughly, working from the outer edges to the center. Finally, dry them with a clean towel. 

If the brick is covered with mildew or lichen, you can use a mildewcide to remove the problem. You can also use a high-pressure cleaner to clean the bricks. Remember to clean from top to bottom, so that the pores are clean and clear for the sealer.
