Right to the point. My home is heated with diesel. A failure of the heater caused a light soot to fill and circulate around the home. Two of my lovely ladies are covered with it. The third was covered and received minimal damage. The soot is small enough that it is stuck in the pores of the tpe. Soap and water is not enough to get it out. Going to take a lot of work and a lot of oil to clean them up.
If your home is heated with diesel take the proper precautions.
