Dry chemical extinguishers are the most common because they can put out class A, B, and C fires. They’re commonly used in industrial, commercial, and residential buildings.

They contain chemicals like sodium bicarbonate, monoammonium phosphate, and potassium bicarbonate. These chemicals leave a corrosive powder that can damage electronics and metal surfaces, so you must act fast.

Follow these steps to clean up the affected areas after using a dry chemical extinguisher:

  • Sweep or vacuum as much of the residue as possible.
  • Create a solution with 50% warm water and 50% isopropyl alcohol.
  • Spray the affected area to break up the silicone. 
  • Let the solution sit for approximately five minutes, then rinse it with warm water. 
  • To clean up the residue with sodium bicarbonate and potassium bicarbonate, mix a solution containing 2% vinegar and 98% hot water. 
  • Wash the area with it. Allow the solution to set for about five minutes.
  • Rinse the area using warm water.

  • Put enough liquid soap in hot water until it’s foamy or bubbly. 
  • Scrub the affected area using a rag or sponge. 
  • Rinse the surfaces and affected areas. 
  • Let the area dry.
