Coat your ice cube trays with cooking spray
One common solution to prevent ice cube trays from sticking together is to use cooking spray. Before filling the tray with water, spray a light layer of cooking spray on the inside of each mold. This will create a thin layer of oil that will make it easier to remove the ice cubes once they are frozen.
Use silicone ice cube trays
If you’re looking for a more long-term solution, you may want to consider investing in silicone ice cube trays. Unlike traditional plastic trays, these have a non-stick surface that makes it easy to remove the ice cubes without breaking apart the tray.
Run warm water over the bottom of the tray
If your ice cube trays have already frozen together, don’t worry! There’s still a way to separate them without breaking them apart. Simply run warm water over the bottom of the tray. This will help loosen the ice cubes and make it easier to remove them from the tray.
Store your ice cube trays in a single layer
Another way to prevent your ice cube trays from freezing together is to store them in a single layer. Avoid stacking multiple trays on top of each other as this can cause them to stick together due to the weight and pressure.
Store your ice cube trays in a dry place
Finally, be sure to store your ice cube trays in a dry place. Moisture can cause the trays to become sticky and freeze together. If you have a particularly humid kitchen, consider storing your trays in a cabinet or pantry rather than on the countertop.
