How to Clean Smoked Walls From Gas Heat

Soot and smoke produced from a gas heater can cover the walls with an oily residue that is difficult to remove. This residue will give off an unpleasant odor and -- if not removed in a timely manner -- will stain the walls permanently. Fortunately, you do not have to live with smoke-stained walls. With a few common and inexpensive household items, you can successfully remove the smoke and soot, restoring the look of the walls.

  • Remove items from the walls. Keep these items -- such as framed pictures and wall decorations -- in a safe location during the cleaning process.

  • Pour 3 gallons of warm water into a 5-gallon bucket. Add 1 cup non-sudsing ammonia, and 1/4 cup liquid dish soap -- that does not contain bleach -- to the water. Mix the contents with a long-handled spoon. Fill a second bucket with cool water.

  • Saturate a sponge in the mixture. Wring out the sponge to remove excess liquid. Begin at the bottom of the walls, and scrub in a circular motion while working upward. Starting at the bottom will help eliminate drip stains.

  • Rinse the sponge in the bucket of clean water when it becomes soiled. Submerge it back into the cleaning mixture, wring out the excess liquid, and continue scrubbing approximately a 3-foot by 3-foot area of the wall.

  • Fill another bucket with clean water. Dampen a cloth in the water, and rinse the cleaning mixture from the 3-foot by 3-foot area of the wall.

  • Use a clean towel to dry the water from the wall. Continue cleaning in 3-foot sections until you have cleaned all the walls.
