Urine Gone ProClean Multi-Surface Stain and Odor Remover Cleaner with UV Black Light, 20 fl oz

I the first three bottles I bought were outstanding! sprayed it on pet stains and the discoloration and smell went away in minutes. I went back and bought two more bottles and I would swear someone switched it out for water (a lot of it) and dish soap. The outside of the spray bottle looks exactly the same but on closer inspection it is a different bottle. The price of these bottles was 1/4 what I paid before. So the question remains... did the company cheapen their formula to reduce the price or did someone use it and return it to the store full of soap and water? Buyer beware. Smell the contents before buying. The real stuff has a strong, but not offensive, clean smell.
