Just thought maybe there is someone who could use this info......on our 'new to us' 5th wheel, the dinette seats were dirty, on reading the owners manuel it stated that all upholstery and drapes should be drycleaned. Well, I washed the seat covers on a gentle cycle and hung them to dry...the result : awesome, no shrinkage, they are clean, smell good and look new
And I didnt have to spend the money at the drycleaners!
