£ 60 Was very cheap , I fail to see how someone can buy a van, machine ,chemicals , fuel ,advertising and insurance and make it to your house , spend 2 hours plus working ,and survive .
To answer your question , it sounds like buffalo , needs the right chems to clean , and extracting with a professional machine , otherwise it could delaminate ,wrinkle, wet the filling and possibly smell bad .
When you say it is worth 100 clean , it is more the cost of a new one and getting it delivered/disposing of the new one that you need to consider.
