Did one yesterday that Swiss laundry had refused to clean,due to possibility of it falling to bit's.
Said I would do it but would not accept responsibility,soaked both sides in urine neaut,gave a good misting of lemon refresh,used double concentrate odour fresh,extracted both sides,in both directions,rug was on a wooden floor,and had started attacking the wood,was wee from a small dog,not sure if that makes any difference,not heard back from customer,but said it may still smell until 100% dry
