Take them to the car wash. My dehydrator has 12 racks. It's worth a couple bucks to clean those babies easily. Wash'em at the car wash, and then bring them home and dip them in hot soapy water in the sink to sanitize them. Take a big garbage bag along with you to the car wash to put them in for the return trip home and to the sink so you're not dripping water all over the place. It's the ONLY way to fly, IMO. Cleaning those racks is the nastiest part of dehydrating, especially if you're doing jerky and the marinade sticks all over them. This takes the work out of it.
