Sorry Mr V but have to disagree.
Cleaned a house for a very well known celeb in Esher Surrey who presents a famous quiz show and got into alot of bother recently due to an indiscretion with a blonde (not his wife) and he had a beige 80/20 twist with lots of accidents from a lab puppy that was one of his kids (he has quite a few in the 18-28 bracket, kids that is). some of the stains were 10 months old. Treated then with debrowner and high PH pre - treat with urine neutraliser and worked a treat. Nice guy but would'nt fix it for me to get on his show. So no chance to make a million but obviously can't mention his name.
