Input:
bought these to add to the 4 trays on my american harvest. Identical to the original trays. Now I can easily do about 5 pounds of jerky at one time. If you're wondering if these are dishwasher safe, it says not to put them in there but I did anyway as sometimes they are very difficult to clean. The dishwasher cleaned them very well but the heat/dry cycle misshaped them slightly. They are still usable but don't stack as nicely and are somewhat twisted (they don't lay flat).. This is after one washing and I stopped it about halfway thru the heat/dry cycle. Im not sure if regular dishwashing will make it progressively worse or if they will get brittle but I suspect it will happen.
