what type of vacuum / extractor are you using ??
some members have found woolite to be too "sudsy" which causes the maps to become soapy. maybe you should look into another type of cleaning product for your carpeting.
i have a little green cleaning machine extractor and this is the cleaner that i use

i make a mixture and then spill it into a bucket, then scrub the carpets with a brush.
then i use the little green to "extract" the water. it may take a few minutes to get most of the water out. be sure not to soak your carpets / mats, as you do not want to have a moldy smell.
i make sure i go in all directions with the extractor to make sure that i get as much of the water out as possible.
