A quick primer on Spotting and urine damage in domestic and commercial carpet. Pet damage is an ever increasing issue in urban life and 30-40+ hour work weeks and small yards. urine damage is treated in roughly three phases. topical, flushing, and invasive. many times simple topical treatment is all that is required. in this situation we use various products, odorcide being one of the most common. this is a great method for multiple smaller spots were cost savings and odor control are the primary concern. all treated areas are then extracted via wand multi-pass and general steam cleaning. stage 2 is similar but more thorough. a special tool that puts all the suction of the truckmount into a small square about the size of 2 hands is used with a rinse-flush method until no discolored water is visible on the extraction. this is a better and more thorough method but it is more expensive averaging 10+ dollars per spot. a great choice for deep penetration areas. lastly we have large volume penetration. basically imagine a great dane who was really thirsty and no one let him out. after this has set in sealing the subfloor via latex paint or urethane sealer. the contaminated section of carpet pad is replaced and both sides of the carpet are cleaned and extracted. this is a worst case scenario situation and often done when there is one large contaminated area.
