No such thing as a dumb question!!! :D:D:D
Also, if you spray the seams after clipping them to damp not wet, you can take a stiff bristled brush and brush them to get the worst of the strings out before laundering. The strings can also clog up your washer, and we all know about the dryer lint screen :D:D:D
I recommend taking them to the laundramat the first time, and the first few times washing them at home, check the lint screen every 10 minutes while drying.
