Grease Magic Thermolock is a solvent-based fogging deodorizer available in citrus or cherry. This petroleum product is designed to be used in a hot “thermo” fogger only. Do not use in a ULV or “cold” fogger. Thermolock is highly effective at neutralizing tough, residual odors caused by heavy smoke damage and structural fire damage, as well as malodors caused by skunk spray, pet odors, food/cooking odors, and more! Thermolock works by recreating the conditions of penetration by malodors, and its fogging nature allows it to reach even the smallest, tightest areas to counteract trapped odors. Available in cherry and citrus!
