5 Tips for Storing a Cooler Long-Term

Clean and dry the cooler thoroughly Wash it with mild soap, rinse well, and wipe it bone dry. Trapped moisture causes mold and warps plastic.

Leave the lid cracked open Prop the lid open an inch or two with a rolled-up towel. Locking it tight traps humidity that damages the cooler.

Store in a cool, dry place Avoid direct sunlight and freeze-thaw cycles. A basement corner or shaded garage shelf works best.

Treat gaskets with silicone lubricant (optional) A little silicone on the seals helps keep them supple, but it’s not required. The open lid is the real trick.

Don’t stack heavy items on top Coolers aren’t shelving. Weight can crack the plastic or damage the lid seal.
