I used this the other day to clean an apt with months old pee stains of varying shades and was unable to get about half of them out. Some looked exactly the same and I felt like a total a-hole after telling the customer I should be able to get most of them(I know, I know, last time I do that)UnDuzIt Unleashed...unreal.
I poured it directly onto the stains(not diluted), and let it sit for about 30 minutes. (I was unable to let it sit for the full hour due to time constraints) I then rinsed with dry slurry to pretty crappy results.
Everyone that's used it swears by this product so I'm wondering where I went wrong. Was it not being able to wait the extra 30 mins or something else?
