Cleaning Soot Off Stone Fireplace

Cleaning soot off a stone fireplace can feel like a tough job, but with the right formulas and a little effort, it’s completely manageable. I’ve dealt with this myself, and trust me, the right approach makes all the difference. Whether you’re tackling black stains or a white stone hearth, these simple formulas will help bring your fireplace back to life! Let’s dive into the steps that worked for me.

1st Formula

Start by creating a thick mixture using detergent or soap, pumice, hot water, and a small amount of ammonia. Apply the mixture generously to the stained area and let it dry completely. Once it’s dry, use a web scrub brush to gently rub off the mixture, lifting away the soot along with it. This method is perfect for breaking down tough, sooty stains, and it worked wonders on my own fireplace.

2nd Formula:

Mix one ounce of table salt, one ounce of soap, and just enough water to form a creamy paste. Using a cloth, rub the mixture onto the soot-stained area and let it sit for at least 10 minutes. Once dry, scrub the surface with a stiff brush to remove the soot. This formula is simple but effective, and it’s great for lighter soot stains that don’t require heavy-duty cleaners.

3rd Formula:

Shave a bar of naphtha soap into a pot, add three quarts of water, and bring it to a boil. Once the soap melts, turn off the heat and let it cool. Then, mix in one pound of pumice and a cup of ammonia. Apply this mixture to the stained areas, let it sit for at least an hour, and scrub it off with a stiff bristle brush. This formula is great for tackling stubborn, deep-set soot stains.

Some Other Ways of Removing Soot

There are some other effective ways you should consider when cleaning soot from your stone fireplace.

TSP

Trisodium Phosphate (TSP) is a powerful cleaner that works well on heavy soot buildup. Simply mix TSP with warm water according to the instructions, apply it to the stained area, and scrub with a stiff brush. Be sure to wear gloves, as TSP can be strong on skin. It’s great for those tough stains that other cleaners can’t handle.

Krud Kutter et al.

Krud Kutter and similar commercial cleaners are designed to tackle tough stains like soot. Simply spray the cleaner onto the soot-covered area, let it sit for a few minutes, and scrub with a soft brush or cloth. These products are easy to use and effective, making them a good option if you prefer a ready-made solution.

Soot-Erasers

Soot erasers are specially designed sponges that lift soot without water or chemicals. Just gently rub the eraser over the stained areas to clean off the soot. They’re ideal for small spots or delicate areas where you don’t want to use liquid cleaners.

Soap, Water and Elbow Grease

Sometimes, the simplest solution works best. Mix warm water with mild soap, then scrub the soot with a sponge or cloth. This method requires more effort but is safe for most clean stone surfaces and effective for lighter soot buildup.

Final Takeaways

Removing soot from your stone fireplace is crucial to maintaining its appearance and preventing long-term damage. Whether you use homemade formulas, commercial cleaners, or simple soap and water, there are plenty of effective ways to get the job done. With a little effort, your fireplace can look fresh and soot-free again. So grab your supplies and bring back the beauty of your stone fireplace!
