Here are questions related to Removing Soot from Walls and Ceiling.

Question: Soot Odour

We had a chimney fire 6 years ago, and a crack appeared in the chimney. We could see it on the outside. We got it fixed just a 1 year ago, but obviously left it too long. The chimney has a bedroom on either side of it, and we can smell soot when the fire is on. The builders could only go so far in the chimney. Soot must of fallen outside the flues. I'm worried about this odour. If I put my nose to the walls I can smell it.

Do you think putting plaster board on the walls in the bedrooms will help, and skim over it?

I agree with the other posters. It is time to get this repaired properly. You should not be smelling soot/smoke in the bedrooms though the walls. I do not think this is a problem that can be fixed with plasterboard. I lived in many different houses in my youth with wood and oil burning stoves and brick chimneys. Never at any time could one smell anything from around the chimney. I would also be worried about carbon monoxide, although maybe that is a non-issue. I don't know.

Try magic eraser! It was the only thing that worked for me. But I also used it on the wood, smooth mantle. .. So I'm not sure for walls or ceilings.

I would try "20 Mule Borax" - I know it works on cigarette smoke. Dilute in water according to instructions and also pour some dry into a small container. Once you've wet your cloth/sponge and squeezed it almost dry dip it into the "dry" borax and start washing. Hope this helps.

Textured walls will be hard to clean. But you could try a dry cleaning sponge. They are chemically treated and work well to clean soot and smoke damage from fires.

You could also try a mix of tri sodium phosphate and water.

Thanks everyone,

Had the same problem--burned candles and got this awful black soot all over the walls and ceiling and carpet edging of my newly constructed house. Was able to easily remove the soot by first vacuuming and then wiping the surfaces down with a dry cleaning sponge--the great part about it is that no water is involved so you don't get streaking on painted walls! :) The sponges get rid of the oily film the soot is made of. I found them online at economical, as one sponge will go a long way---and it doesn't take long to clean. Since then, I the routinely clean the whole house annually with the sponges. Good Luck!:)

Rubbing alcohol on a clean rag. If you put it in a spray bottle you will get drips.

My husband and I are buying a house. On one of the visits to the house we saw what we thought was dirt on the walls and the carpet. Since then we have discovered that it is more likely something called black soot deposition. There are many causes, like a gas stove, fireplace, etc., but from the research we have done we think it is from candles burning. Every time we have been there candles have been burning. My question is how do we clean this soot off of the walls and the carpet? Thank you,

RE: Black Soot on Walls

Before you sign anything, make sure the black marks are not mold. The sellers could be using candles to cover the odor, and/or making you believe that the black is from the candle, rather than the mold. Candle soot does not typically get into carpets, so I'd be very concerned. (08/12/2005)

RE: Black Soot on Walls

Sounds like there is a cover up going on. In TX, the buyers pay to have an inspector come in and check out the house from stem to stern. Many years ago, they didn't have much training, but now there is an official check list and these inspections can take hours. I'd like to suggest you find yourselves a house inspector because it is cheaper in the long run to not buy that house, than to get one with mold.

Before you select an inspector, ask to see the check list and about their training. You don't want someone to pop in and leave a half hour later like we used to have done years ago. You could even ask the sellers to pay for the inspector's bill as a condition of the purchase and see if they panic. (08/12/2005)

RE: Black Soot on Walls

I agree with Holly. A house inspection costs about $350 (in the Pacific Northwest) but it is well worth it. They go over the home thoroughly top to bottom and check everything. They give you a written report which can help with negotiating the price if there are problems. I'd also recommend this to anyone getting ready to sell a house because you can get problems fixed before an inspector goes in for the buyer.

As for cleaning off soot, the best thing to do is try to brush it off. As soon as you use water it can just spread it around. Get as much off as possible while it is dry and then use a good all purpose cleaner or possibly even a magic eraser.

How do you get soot from ceilings and walls off after a kitchen grease fire? I have tried the commercial cleaner with no luck, and also tried Mr. Clean and ammonia. Please help.

RE: Black Soot on Walls

I would wash the walls and ceiling with TSP, which is available in hardware stores, then paint the walls and ceiling. (03/25/2009)

RE: Black Soot on Walls

I'm commenting on 2 different people's questions here. If the black marks are from a fire, try making a paste of baking soda and water. Use a soft washcloth to clean it off.

I agree with the person who said the candles burning may be covering up the smell of mold. I go to a lot of estate sales, so I've been in lots of people's homes. You'd be surprised by the number of people who have problems with mold. Make sure there is good drainage around your house to prevent mold. Never buy a house with a mold problem. There may be mold in the walls and other areas you can't clean. Bleach kills mold. (03/27/2009)

My boyfriend turned the wrong burner on the stove on, which happened to have a plastic Folgers coffee can (empty) on it. Needless to say, the can melted into the stove (which we got clean), but the painted walls and ceiling are covered in soot. Are there any suggestions on cleaning this up without having to repaint (its a rental house).

Thanks ahead of time.


RE: Soot on Painted Wall

Use ammonia (I prefer sudsy ammonia) in a bucket of water and wash from the bottom up. (03/16/2005)

RE: Soot on Painted Wall

I received this idea from the firemen when my brother-in-law was involved in a small fire. Mix washing soda, vinegar, and ammonia together to a bucket of water. Then wash the wall with it. This combination works well to remove soot and smoke smell from clothing or curtains, etc. (03/16/2005)

How do I remove black soot from walls?

By Molly from Philadelphia, PA

RE: Soot on Painted Wall

A painter shared this with us and it has always worked for me. Get a rag and wet it. Shake some Comet (Ajax, whatever cleanser) on it, make a paste and rub in circles all over the area. Then wipe with water when it is clean. This is great on spot treatments. It will probably take a bit of elbow grease for such a large area, but it should work without hurting the paint. Good luck and let us know how you did! (05/18/2010)

RE: Soot on Painted Wall

I'd get some rags [lots] or paper towels ready, and make a solution of soapy water, with Dawn or a fairly strong soap, you know how some are mostly water. If you wanted you could dissolve laundry detergent in hot water.

The first layer is going to be very messy. You want to get lots of soap and water on the wall with a scrub brush or sloshy rag, but be prepared to catch the soapy water right away with more rags. Do just a small spot at time, about 4-5 inches in diameter. Work towards center of spot, don't just move the soot around. The first batch of rags/towels probably will have the majority of the soot, just toss them and don't try to rinse them out, it will just spread soot all over the place. Second batch of rags/towels use fresh soapy water, and repeat.

Soot is black carbon with an oily quality. You just want to remove it, not spread it. So wipe and scoop towards the center of the area you are cleaning. Toss as necessary. Finally you will get down to the bare wall again, maybe wash/wipe with something that smells nice. When it dries look at it again. Does it need more washing?

One can often find a paint recycling center where you can get paint for free or almost free. You might not have to paint the whole room, just the wall behind the stove. Rollers can be found at dollar stores. It doesn't have to be a spendy deal. Craigslist might have free paint as well. (05/19/2010)
