Keep your esky lid shut!!
Seems like an obvious one but is amazing how often we see the lid is not secured correctly or the lid is opened unnecessarily…esp with kids.

Obviously more frequent lid openings will release more of the trapped cold air inside the box. Each time the lid is opened, the temperature rises rapidly and then it takes another few hours to go back down to the temperature it was prior to the lid opening. The aim is to open the lid and get your goods out as quick as possible without letting too much cold air escape.

Factors to be considered are:
Good wall thickness on your esky

Good quality lid seal

Lid is latched & strapped, adding compression to the seal

Filling any unused air space in the esky with towels etc

A full esky will maintain temperature and hold ice better than an empty or partially empty esky!

For optimum results, it’s best to store your ice quickly!!

Bags of ice must be immediately moved from the freezer to the ice box/esky. Long delays between moving the ice into the ice box/esky will already begin melting the ice. (Even if it’s 5-10 mins). This 5-10 mins of ice melt could be equivalent to 1-2 +days of lost ice retention.

Just remember that it’s an insulated ice box/esky and not a fridge.
