Content: Once steam starts coming out of the machine, run the applicator down the wall. Frequently change out the cleaning cloth on the applicator to keep from spreading the soot and smoke back onto the wall. A steam cleaner can also help to loosen caked-on smoke or its sticky residue. Scrape off the sticky residue from the walls into a bucket. Rinse clean with a dampened sponge or cloth. Advertisement
Furnace Smoke
Though some states regulate or prohibit the use of trisodium phosphate, new versions make it safer to use if you can buy it in your state. But wear gloves and a face mask for protection when cleaning with TSP, because it is a powerful chemical cleaner. To clean furnace smoke buildup, dilute one heaping teaspoon of TSP in a gallon of warm water, mixing it thoroughly until it dissolves. Wipe the walls from the top down with a sponge wrung out after you dip it in the solution. Follow by rinsing with a clean sponge wrung out in clean water.
