Walls

• 1). Lay a drop cloth over the floor under the walls with the soot buildup to protect the floor from the cleaning solution.

• 4). Repeat Step 3 until you have thoroughly cleaned the soot off the wall.
  
  
• 5). Wipe the cleaning solution off the walls gently with a clean cloth dampened in cold water.
