i am helping a friend clean some dog piss spots from his rental just to see the results, the carpet is an off wht nylon and it has these brown piss spots thru out the house, after cleaning i went back and poured prochem odor rescue into the spots and left for 30 mins and ext with water claw, seen all the nasty in the claw and some spots went away but some are still brown stained, so we are wonderin how to deal with the brown
:shock:
