Hint: Pretreat ice cube trays with Pam™

To help ice cubes easily pop out of plastic ice cube trays, pretreat the trays with Pam™ or similar product. Treat dry trays by spraying the interiors very lightly. Spray them in the sink or inside a dishwasher to restrict the spray. Then rinse the trays under running water and let them dry before filling. The treatment leaves no visible residue on the ice. Repeat treatment as needed to retain effectiveness.
