Anyone ever have to remove the rear seat on an S60? The wife had a container of kerosene in the trunk this winter and it tipped over and spilled. Most of it was caught by the Weather Tech trunk liner but apparently a bit went over the edge and under the seat. We've been hoping the odor would dissipate but after 3 months it looks like I am going to have to replace some or all of the seat and maybe carpets. Any help would be appreciated.
