With stone, there are microscopic pits found naturally that form crevices for dust, dirt, and soot to accumulate and form stains. Over time, these can eventually lead to chimney fires if you don’t clean them out. To ensure the safety and efficiency of your fireplace, you should ensure to clean out your stone fireplace on a regular basis, which is easy and cheap to do. Read on for a curated list of tips on how to clean your stone fireplace with household supplies that you likely already own. 

You will need these tools

In order to protect the living spaces and items around your fireplace, you should be sure to pre-clean the firebox, which is the place where the fire burns, and its surroundings before attempting a proper cleaning of the fireplace itself. You will need the following materials: 

Drop cloths, plastic tarps, small shovel between, 15 to 30 inches long, metal container, gloves mask for dust plain water, a vacuum cleaner with a brush attachment.

Remove ashes and dust 

Allow for at least 12 hours between the time you put out the last fire to the time you want to clean the fireplace. In the interim, you can lay out the drop cloths on the nearby floor and over furniture to protect them from cleaning fluids which are often harsh acids or alkalis, and from any airborne dust and dirt. 

After at least 12 hours have passed, you are ready to clean out the fireplace. Put on gloves and a dust mask to prevent your nose and skin from being irritated by the dirt. Using the shovel, scoop out ashes in the fireplace into the metal container, ensuring to cap the container so the ashes do not fly out. Fill the container with cold water and store it away from any flammable objects until you can discard them. 

Using a vacuum cleaner, suck out any surrounding dust that was not scooped out. This will aid in speeding up the cleaning process. With that, your pre-clean is done. 

Assessing the stains

If you use your fireplace almost daily but fail to do routine cleaning, there are bound to be some heavy deposits of dirt and soot that form stains. These stains can prove to be hard to remove and will need the use of more harsh cleaners. Prior to cleaning your fireplace with the solution, apply it to a small spot that is not easily visible. This helps you ensure that your cleaning agent of choice does not leave marks or have any chemical reactions with your stone fireplace as different kinds of stones would have different reactions. This should be done 24 hours ahead of the time you intend to clean. 

Use a Homemade Cleaning Recipe

Homemade cleaning recipes can help to remove stains, and they tend to be less harsh compared to commercial cleaners. Here is a gentle one that works wonders:

1.-Dilute a quarter-cup of dishwashing soap or other household soap with lukewarm water of the same amount. Stir the solution well to ensure that the soap has dissolved. This will be sufficient if your fireplace is not heavily coated with soot (Which the pre-cleaning routine) should have taken care of. 

2.-Put on gloves and a mask to avoid irritation from dirt and dust. Using a clean scrub brush, dip it in the pre-mixed cleaning solution. Use the brush to scrub the fireplace all around, loosening any dirt and grime that has been trapped in crevices within the stone. 

3.-Using a fresh bucket of cold water, take a clean rag and dip it in. Wipe the fireplace with the rag to wipe off soap suds and any remaining dirt. 

4.-Using a separate cloth, dry the fireplace out as best as you can. Let it air-dry for at least a day before lighting it again. 

Avoid Harsh Chemical Cleaners

As much as harsh cleaning agents seem like they’ll do the trick for an especially dirty and grimy fireplace that hasn’t been cleaned in ages, avoid using strong chemicals such as bleach, as these can cause the stone to fade. You’ll also want to steer clear of any cleaners with citrus in them, as those are naturally acidic and can destroy the stone. If you find streaks, abandon the cleaning agents or solutions and try using water first.

Ensure that any cleaning agents you use in cleaning out your fireplace are non-flammable. This is not just a matter of staining your beautiful stone fireplace, but more importantly, can be a fire hazard that could cost you your house and home. 

Do Deeper Cleans Occasionally

The time to do deep cleaning is definitely before the first fire of the season that you intend to use the fireplace, so as to eliminate any creosote built-up from previous fires.

On the other hand, if you seldom use your fireplace, you can wait until there are around eight inches of build-up before doing a deep clean. 

You can create your own solution to use for a deep cleanse as well, by mixing one gallon of lukewarm water with half a cup of trisodium phosphate that can be bought from the local DIY shop or supermarket cleaning department. This will be stronger than simply using dish soap and mixing it with water. Be sure to avoid contact with your skin when using this solution. 

Buy the appropriate cleaner for your area
