Serum SR (Smoke Remover) is formulated to remove heavy smoke build-up in fire-damaged structures. It's chemistry lends itself to be very agressive yet safe to use. It is based on the tried and true use of a small amount of caustic and a water-soluble solvent from the alcohol family to dissolve, sequester and rinse heavy, heated-on smoke that may exist in fire-damaged structures.
Simply spray Serum SR onto all affected areas, allow ten minutes dwell time, then rinse off using a low-volume, high-pressure washer.
