Stop in for a cup of coffee

So I tried dehydrating some of our veggies and fruit, but after the recommended time and times, they were are stuck to the trays. Mines just one of those multi stack jobs. Any suggestions?
If you put them direct on the wire you will never get them unstuck, grab either one of the pictured style mats from Amazon and they release right off. There is likely many versions, these are the two we use.
