Applying a mixture of enzyme cleaners and deodorizing agents is effective for removing pet odors from upholstery due to the specific nature of how odors are created and how they can be neutralized. Pet odors are often caused by organic materials such as urine, feces, and other biological substances that contain proteins. Enzyme cleaners are designed to break down these proteins, effectively eliminating the source of the odor rather than merely masking it.

In contrast, high-temperature steam can help in sanitizing the upholstery but may not be as effective in breaking down the chemical structure of pet-related impurities. While it can aid in cleaning, it doesn't specifically target the enzymatic breakdown required to neutralize odors.

Using vinegar and baking soda can help to some extent due to their natural deodorizing properties; however, they may not be as effective as enzyme-based solutions for stubborn pet odors. This method works more as a general deodorizer rather than addressing the underlying biological causes.

Covering upholstery with fabric fresheners might temporarily mask the fragrance but does little to resolve the issue of odor at its source. It’s an ineffective long-term solution and may not provide the thorough cleaning needed for better odor management.

Thus, using a mixture of enzyme cleaners and deodorizing agents stands out as the most comprehensive method
