I used the pet spot clean solution on my neighbour's dog's diarrhoea mess on her carpet. There must have been 15 spots of varying size and the carpet came up like new! It really was impressive. Both of us have order more of the solution and wouldn't be without it. My neighbour, who has kept pets for years and used many different products for mishaps told me Bissell pet solution was streets ahead of anything she has used. So thanks for the help!
