Is fire extinguisher powder corrosive?
The most common agents used in dry chemical fire extinguishers are monoammonium phosphate and sodium or potassium bicarbonate. Time is of the essence when this type of extinguisher is used because these powders can be corrosive to metals and can lead to further damage if not cleaned up quickly.
How do you remove fire extinguisher powder?
Clean Up Dry Chemical Fire Extinguisher Residue Vacuum or sweep up loose debris. Spray stuck-on residue with isopropyl alcohol diluted 50 percent with warm water. Let the solution sit for several minutes, and then wipe with a damp rag.
