A chimney sweep clears creosote and soot buildup from the flue — necessary maintenance for wood-burning fireplaces and slow-combustion heaters, which are common in the cooler parts of the Sutherland Shire including Engadine, Heathcote, and Waterfall. Even when the fireplace opening is covered during the sweep, fine carbon soot particles escape into the room and settle on carpet. The fireplace hearth rug and the carpet within 2–3 m of the fireplace are most affected, but soot can travel throughout open-plan areas via air movement.
Why soot requires a different approach
Chimney soot is fine carbon particulate with an oily carrier from combustion residue. Unlike regular dust, soot has two components: the dry carbon particles (which vacuum away) and the oily combustion residue that the carbon particles carry (which requires solvent treatment after vacuuming). Applying water or dishwashing liquid before vacuuming the dry soot away causes it to smear and set, creating a dark grey stain that is significantly harder to remove. The correct sequence is always dry removal first, solvent treatment second.
What you need
- Vacuum cleaner (ideally with HEPA filter)
- Isopropyl alcohol
- Dishwashing liquid
- Warm water
- White cloths only (soot shows immediately if the cloth is soiled)
- Baking soda (for deodourising)
- Spray bottle
Removing soot after a chimney sweep
- Do not touch or wipe the soot dry — this smears it into the pile surface.
- Vacuum the settled soot with slow, overlapping passes. A HEPA-filter vacuum prevents fine soot particles from exhausting back into the room air. Take two to three passes over each area.
- Apply baking soda over the affected carpet area and leave for 30 minutes to absorb the residual oily combustion residue and deodourise.
- Vacuum the baking soda away with the same slow-pass technique.
- Apply isopropyl alcohol to a white cloth and blot any remaining dark marks. The alcohol dissolves the oily soot residue. Use fresh cloth sections as each becomes soiled.
- Follow with dishwashing liquid solution, blot with warm water to rinse, and blot dry.
- For heavy soot coverage on the hearth rug, the above steps are a holding measure — a professional extraction clean achieves more complete soot removal from deep in the pile.
Cover and protect before the sweep
Ask your chimney sweep to use a drop sheet over the hearth carpet and to tape a dust sheet across the fireplace opening during the sweep. Most professional chimney sweeps carry these as standard equipment. If yours does not, lay your own plastic sheet on the carpet within 2 m of the fireplace before the sweep begins — this prevents the majority of soot fallout from reaching the carpet.

Frequently asked
The soot has gone through the whole room and the carpet looks grey. Is there a way to restore it at home?
Widespread grey soot coverage can be significantly improved at home using the vacuum-baking soda-vacuum-alcohol sequence. The improvement is often dramatic after thorough vacuuming alone. However, very fine soot particles embed in the pile at a depth that home vacuuming cannot fully reach — a professional hot-water extraction clean after your home pre-treatment achieves the most complete restoration. Even partial home treatment before the professional clean improves the outcome by removing the surface layer.
The chimney sweep left black footprints on the carpet going from the fireplace to the door. How do I treat these?
Footprint soot marks are concentrated deposits on specific spots rather than overall coverage. Treat each footprint individually with the isopropyl alcohol blotting method after vacuuming. The defined shape of a footprint makes targeted treatment straightforward — work from the outside edge of each print inward to prevent spreading. Use white cloths so you can see when the soot transfer to the cloth has stopped before moving to the dishwashing liquid rinse step.
There is a creosote smell in the carpet after the chimney sweep. How do I remove the odour?
Creosote odour in carpet after a chimney sweep comes from the oily combustion residue in the soot. Baking soda is the first treatment — apply generously, leave for several hours or overnight, and vacuum. White vinegar misting (lightly applied with a spray bottle, not saturated) neutralises the acidic soot odour compounds. Activated charcoal bowls placed in the room for 24–48 hours absorb residual airborne odour. For persistent creosote smell that home treatment does not clear, a professional hot-water extraction clean with a deodourising treatment is the most effective solution.
The hearth rug has heavy soot damage. Should I clean it on the carpet or take it outside?
Take the hearth rug outside for initial treatment. Shaking and vacuuming a heavily soiled hearth rug indoors releases soot particles into the room air, which then re-settle on the carpet and other surfaces. Vacuum the rug outdoors first, lay it on a clean surface, and treat with the baking soda and alcohol steps outside. If the rug is machine washable, a cold wash cycle after the pre-treatment removes much of the remaining soot. For wool or delicate rugs, professional rug cleaning is the appropriate route.
