7 Ways To Clean A Stone Fireplace

A fireplace will always be a beautiful addition to a home. It adds a calming aura to any home. It can also potentially increase a house’s resale value by up to 15%. There’s just one downside to it; it requires frequent and intense cleaning, even more so when it is a stone fireplace due to the porousness and irregular shape of the rocks.

Fireplaces easily accumulate dirt, soot, grime, and all sorts of icky stuff. The smoke from the fire is bound to leave a blackened spot in the fireplace, and when it is left unattended, it becomes an eyesore. The good thing is, it is actually pretty easy to get rid of them.

Before You Start Cleaning a Stone Fireplace

We recommend you do a little pre-cleaning preparation before deep cleaning your stone fireplace. You do not need to do much; simply cover your furniture or anything you do not want to get stained. If you have items beside your fireplace, remove and keep them covered as well. 

Ways To Clean A Stone Fireplace

  • Remove Ashes Frequently

It is advisable to dust, clear out ashes and every other burnt waste every week. This will not only help make your fireplace look better, it will also protect your health. The air released from burning wood can be extremely harmful to your lungs and heart as it is filled with toxins. 

Be careful while doing this though. Wait until the ashes are no longer hot and the fire has been put out before you proceed to clean. The recommended time is at least 12 hours after your last fire.

  • Clean Your Stone Fireplace With Vinegar – White Vinegar

There are some cleaning agents in vinegar that can help with cleaning your stone fireplace. It is a cheap and gentle method, so you don’t need to worry about breaking the bank.

First, thoroughly mix a cup of vinegar with one gallon of water in a bucket. Grab a spray bottle and pour part of your mixture into it. Spray the surface of the stones and leave them to sit for a few minutes before scrubbing.

Next, dip your bristled brush into the leftover mixture and scrub the nooks and crannies of the stone fireplace. Once you are satisfied with the way it looks, repeat the same process but with a cleaning rag. Dip it into the vinegar mixture and wipe the surface of the stones.

Finally, wet a cleaning towel with plain water and wipe down every part of the stone fireplace, its inner and outer parts. Ensure that it is completely dry before starting another fire.

  • Clean Your Stone Fireplace With Muriatic Acid

Muriatic acid is a really strong, heavy-duty chemical that can be used to clean stone and other masonry items. You must read the instructions on the body of the chemical before using it. 

Mix one part of the acid with ten parts of warm water. Mix it thoroughly, dip your bristled brush into it and scrub all parts of the stone fireplace with it. After that, dip a cleaning towel into warm water and wipe down the fireplace to remove any leftover residue from the solution. 

Let it dry completely before starting the subsequent fire.

  • Clean Your Stone Fireplace With Trisodium Phosphate

Trisodium Phosphate or TSP is another chemical and bleach that is safe to use in cleaning stone fireplaces. For this method, simply combine half a cup of TSP with three parts of hot water. It should be hot enough to at least dip your fingers in without it scalding you. 

Take out the grate/andirons and use a stiff-bristle brush that has been dipped into the TSP solution to scrub it down thoroughly. It is best to do this outside if you do not want all the soot stuck in it to fall on your carpet and furniture. Dampen a cleaning rag with plain water and wipe off any solution residue on the grate. Set it aside to dry. 

Scrub off any excess dirt stuck to the stone fireplace walls with a dry brush and vacuum the ones that fell on the floor during the process. 

Pick up your stiff-bristled brush again and rinse it clean of the grime from the grate. Dip into the TSP solution again and thoroughly scrub the body of the fireplace. Take the same cleaning rag, dip it in clean water and clean off the solution residue. 

If any stain remains, create a more potent TSP mix and repeat the same process.

  • Clean Your Stone Fireplace With Dish Soap

We know that some of you might be skeptical about using the chemicals listed above, but that is okay. If you do not want to use them, go for your everyday dish soap instead.

Bear in mind that, unlike the other chemicals, dish soap will not deep clean your stone fireplace. It will only help keep it looking nice and reduce the amount of work you will have to do on the days you want deep clean. You still have to put on safety gear, even if it’s just dish soap.

  • Clean Your Stone Fireplace With Detergent

You do not want something as harsh as the chemicals, but you want something a bit stronger than dish soap. Not to worry, pick up your detergent. 

Mix one cup of detergent, three tablespoons of table salt, and three parts of warm water. Dip a plastic or rubber scrubber into the mixture and vigorously scour the stone fireplace. Use a damp cleaning towel to wipe and rinse off the solution.

  • Clean Your Stone Fireplace With Ammonia

Ammonia is a potent cleaning agent. It can be used to clean a variety of things, including paint stains on clothes. If the detergent does not work and there are still minor stubborn stains here and there, all you have to do is add ammonia to the mixture. 

The substance can sting, so we advise that you put on all necessary safety gear to protect yourself. Repeat the same cleaning process and let it dry.
