Looked at an area rug today, it's a 12 x 9 jute wool area rug with browning spots visible. Customer said she had another cleaner clean the rug and it took 4 days to dry. Now there are maybe 2 brown spots on the rug but it does not seem consistent with what the rug would look like if the entire rug was wet for 4 days. I did the old sniff test to the brown areas and they smelled of dog urine, (two little yorkies snapping at my feet as she is telling me this). I really don’t think she was telling me the entire truth. Anyway, what would be some cautions to look for in cleaning this rug? I will post pictures of the rug when I pick it up.
