Probably a long shot but.......................Had a call from a lady asking if I could get old dog wee stains out of her carpet,as I haven't had a great deal of success in the past with these I popped round to her place.
Its a luxury apt complex with cream carpets all through.Didnt do a burn test as I forgot my gear but got a fibre and it floated in water so Im pretty sure its PP.There are dozens of urine spots all through the aptment some of which shes had a go with herself with the Vanish and 1001.(she said the VET told her it gets urine out

)
I followed the Prochem stain advice and soaked a couple of stains,one that had been treated with Vanish and one that hadnt, in FF rinse and hot water mixed 50/50,left for 10 minutes.Extracted and neither would budge.
I had a tearful lady fearing that she will lose her £3000 deposit when she moves next month,so said I would ask for any other advice on here.It amazes me that people will leave dog urine in carpets for weeks/months and not do anything immediately so it serves her right I suppose.
Anyone got any other suggestions please.
Thanks Wayne
