An enzymatic cleaner is the most effective method to remove pet pee odor from a carpet. This sort of cleaning helps to neutralize and eliminate odors. For the optimal outcome, absorb as much pee as possible with paper towels. Then, spray the carpet with the enzymatic cleaner and allow it to soak. Finally, remove any lingering stains and odors from the carpet by blotting up any remaining cleaning. You may need to clean the area twice for persistent stains or odors, especially if you don’t want your dog peeing there again.
