What should technicians avoid guaranteeing if a pet animal is present during urine odor removal?

Technicians should avoid guaranteeing the removal of all odors when a pet animal is present during urine odor removal because pet urine can contain a variety of odor-causing compounds that may be resistant to treatment. The presence of these compounds poses a challenge, as some odors are deeply embedded in materials like carpet or flooring, or they may have spread into adjacent areas, making complete odor removal uncertain. Additionally, ongoing behaviors of the pet, such as returning to the same spot to urinate, can perpetuate the odor issue despite the technician's efforts. Instead of making absolute guarantees, it is more practical to set expectations and educate clients on the possibilities of odor control, leading to more satisfactory outcomes.
