Your seat covers may be machine washed, but not dried. Use lukewarm water and mild detergent. Do not use liquid fabric softener or bleach. Coil and bind the fastening straps with a rubber band, then wrap the coil in a plastic sandwich bag and secure with a rubber band. This way the straps will not flail the seat covers and make a mess in the tumbling process. Hang dry.
