The short answer
Assess the Damage First
Before touching the painting, examine it in good light. Look for cracking, flaking, or lifting paint. If the paint is unstable, any cleaning attempt can cause more harm. In that case, stop and call a professional art conservator. They have the tools and training to handle fragile surfaces.
Check whether the soot is dry or sticky. Dry soot brushes off more easily, while sticky soot from smoke residue may require special solvents. Never rub the surface, as that can push soot into the paint. Work slowly and in small sections to avoid spreading the mess.
Gather the Right Tools
You need a soft, natural-bristle brush, like a makeup brush or a clean artist's brush. Some people use a dry microfiber cloth, but be gentle. A vacuum with a brush attachment can help, but use low suction and keep the nozzle slightly above the surface. Never let the vacuum touch the paint directly.
Alternatively, use a soft sponge or a cotton swab for tiny areas. Avoid household cleaners, water, or any liquid unless a conservator recommends it. These can dissolve the oil paint or leave residue. For large soot deposits, consider contacting a professional who handles on-site contents cleaning.

Brush off Loose Soot Gently
Hold the painting upright or lay it flat on a clean surface. Use the brush with light, sweeping strokes, moving from the center outward. Lift the brush frequently and tap it to remove collected soot. Do not press hard, as that can embed particles into the paint.
Work in small sections, checking your progress often. If the soot is stubborn, do not keep scrubbing. Instead, stop and consider a dry cleaning sponge, available at art supply stores. Test it on a corner first. If paint comes off, stop and consult a pro.
Handle Smoke Residue Carefully
Smoke damage often leaves a greasy film that dry brushing cannot remove. In such cases, a professional art conservator may use specialized solvents or gentle cleaning methods. Never attempt to wash the painting with soap or water, as that can cause irreversible damage.
If the painting is part of a larger disaster cleanup, the pros can help with the surrounding contents, like frames or storage areas. They can also assist with deep cleaning after disasters, but the artwork itself should be left to an art expert. Keep a list of local conservators handy.
Prevent Future Soot Damage
After cleaning, protect the painting with a glass or acrylic frame to block dust and soot. Keep it away from fireplaces, candles, or kitchen vents where smoke can settle. Regular dusting with a soft brush helps maintain its condition over time.
Consider storing valuable art in a climate-controlled space during winter storms, as coastal nor'easters can bring moisture and soot from heating systems. For severe damage, professional on-site contents cleaning can address the environment, but the painting still needs a conservator's care.

Can I use water to clean soot off an oil painting?
No, water can damage the oil paint and cause the canvas to warp or shrink. It may also push soot deeper into the paint. Use only dry methods like a soft brush. For stubborn soot, rely on a professional art conservator.
What if the painting is very old or valuable?
For valuable or antique paintings, do not attempt any cleaning yourself. A professional art conservator can assess the condition and use safe techniques. They may also recommend stabilizing the paint before removal. Always seek expert advice for irreplaceable pieces.
Can water damage pros clean my oil painting?
Water damage pros handle contents like furniture, upholstery, and household items, but not fine art. They can clean the surrounding area and storage. For the painting itself, contact an art conservator who specializes in artwork restoration.
