I am not the neatest person in the world but I am amazed at the rate the seat covers in S60 which has fabric covers get dirty. Practically a drop of pure water leaves the most unbelievable marks on the fabric. I have never seen anything like this in any of the many badly made cars I have owned (and I have owned a jeep so that is saying something).

Is it only my car or all fabric car seats in Volvo are like this. This does not fit with the well planned and well build of everything else in this car.
Does anyone have any suggestion for cleaning the seat covers? I have tried many commercial brands sold in Canadian Tire (very large chain in Canada) and nothing has worked.

Thanks in advance.
