Has anyone yet suggested to remove the seat covers and put them through the laundry machine .... on Hot/Medium/Cold ... Normal or Gentle, your choice.

The seat covers are NOT that hard to remove ... unless you have captain chairs ....  removing the arm-rests can be a bit tricky, but not all that hard (see the archives for directions).

Another plus to actually removing the seat covers, is that one can then clean the grim-soaked foam.   m2cw   m
