How do I clean soot off the brick or stone around my fireplace?
Vacuum or dry-brush the loose soot first, then scrub the brick or stone with a brush and a masonry-safe cleaner — warm water and dish soap or a TSP substitute for light staining, a dedicated brick-and-soot cleaner for heavy buildup. Work top to bottom, rinse, and always test a hidden spot first. Skip acids and pressure washers indoors.
Start dry, then go wet
Wet soot smears into the pores of the masonry and gets harder to remove, so knock off the loose material first with a vacuum or a dry brush. Lay down a drop cloth while you're at it — soot runoff stains floors and carpet fast.
Then scrub with a soft-to-medium brush and your cleaner. For a light film, warm soapy water or a TSP-substitute solution does it. For years of buildup, reach for a purpose-made brick and masonry soot cleaner. Work top to bottom so drips fall onto dirty surface, rinse with clean water, and blot.
Match the cleaner to the surface
Brick and most manufactured stone tolerate mild alkaline cleaners fine. Natural stone is the one to be careful with — marble, limestone, and travertine, the kind you'll see on higher-end mantels, are acid-sensitive. Never use vinegar or any acidic cleaner on them; it etches the surface permanently.
When you're not sure what you've got, default to mild soap and water and always test a low, hidden corner first. Sealed stone releases soot far more easily than raw, porous stone.
When cleaning isn't the real fix
If soot keeps darkening the wall above the opening no matter how often you clean, the fireplace may be spilling smoke into the room — a draft or damper issue that's worth having us look at, common in our downdraft-prone mountain terrain.
A heavily stained surround is also one of the most common reasons people call about a refacing. New stone, tile, or stacked stone — installed with clearances honored — can transform the whole room. Call (828) 545-0525 or visit our Asheville showroom to see options.
