Flush with tepid or cool water. Why increase the odour problem by cleaning with heat unless you like basking in the fumes.
Make sense( to lower water temperature). I'm blessed
( cursed? ) with customers that need help with urine treatment ( human and pet) I'm no stranger taking care of #1, #2, and #3 sometimes in combination. The worst of the worst are cats finding their way into the walk-in closets . I've tried many products among them CTI' s OS-1 , Un-duz-it, Bio- release, Skunk-out, and Joedorcide. I also tried CTI Odor modifier, and rest of their urine treatment products.
Bio-release, Joedorcide and USR multi-phase by Clean Master are my favorites. Urine removal requires a lot of patience, especially when homeowners are not planning to get rid of their carpet. Spray, stomp it, let it dwell, rinse, extract ( water claw helps), and repeat. In acute cases , I shoot a few oz. of urine treatment with a syringe in the padding. I always take time to dry the surface ( did I mention patience?) I have to confess that after all that, I use disinfectant ( always along the baseboards ) I believe that Axel70 will improve over time, will trust his instincts, and urine removal becomes his second nature.
I apologize in advance to those who might have a problem with my " poetry" .
