I try to drop my machine off whenever we're out of town for a few days, so I don't miss it while it's gone. I have a service maintenance agreement, so it doesn't cost anything for cleaning and servicing, and the dealer also checks to see if there are any new software downloads for my machine. I would really like to see how much lint is accumulating in those areas I can't get to. Maybe I'll ask the technician to let me look next time.
