These pictures are from a carpet cleaning in Tampa FL. The land lord of this rental was getting the condo ready for the next renter. They had previously cleaned the carpet with a rental machine. This time they decided to try a using Chem-Dry of Tampa FL to see if they could get better results.
On the upper floor of the condo is two bedrooms and a hallway. The smaller bedroom had some carpet spots, including this pet urine stain in the middle of the doorway. They had tried to clean it themselves but it had only gotten worse after the cleaning. That's because urine is one of the more difficult substances to remove from carpet. When urine dries it crystallizes and starts to absorb moisture from the air and surrounding material. The urine crystals, sometimes call urine salts, take on the consistency of wet sand and becomes very difficult to remove from carpet. The urine that dries in the carpet pad underneath cannot be removed through an ordinary carpet cleaning. It needs to be treated with a urine remover to treat the carpet pad problem.
The condo owner was thrilled that the urine and other spots came out during the carpet cleaning. Chem-Dry has an excellent solution for getting rid of pet urine stains in carpet, it's called Pet Urine Removal Treatment (PURT). PURT removes up to 99.9% of urine odor in carpet and 99.2% of the bacteria associated with urine in the carpet.
