So I cleaned the carpet in my house this weekend.  Got down on my hands and knees and a blacklight, searching out areas where my yorkie let loose.  There were a lot of spots and my first thought that was that there is no way I was going to get it clean.  I filled up my spot bot with hot water and a little Simple Green multi purpose cleaner.  I was so impressed with how the glowing spots of pee (from being under the blacklight) came up so easily.  Simple Green worked so well, that I just had to get on here and post about it so that others can try it in the future.  I already use Simple Green to replace my windex, and most other common household cleaners and it is a great multi-purpose cleaner, but now I am sold on it for life.  My house no longer stinks like pee. Not that I am saying this can replace a good steam cleaning, but it will definately get you by without stinky carpet until your next professional cleaning.
