Carpet deodorizer is a specifically formulated odor counteractant that penetrates odor causing the surface to eliminate the odor at its source. Odor sources such as stomach acids, smoke, feces, urine, blood, etcetera – will require different treatment. In general, all deodorizing requires full cleaning of the surface to get rid of odor-causing material/source. Deodorizer is applied using different techniques to get fully in touch with the source and eliminate odor. Some situations, such as urine staining may have penetrated deep into the carpet backing, carpet cushion, and/or subfloor. These cases may require additional procedures to fully eliminate odor and deodorizing surfaces may require multiple treatments. In some instances, full odor removal cannot be guaranteed.
