Title: Don't put them in the dishwasher!
Review: I bought 4 of these trays and stuck them in the dishwasher to clean them before use. Any of my other food grade silicon I can stick in the dishwasher just fine. Well, these warped and won't even sit flat on the counter anymore. No where on the Fred & friends website, the package or the tray does it state it is not dishwasher safe.
