In theory, defrosting your freezer is simple: turn it off, take out the food, wait for the ice to melt, sponge, dry, and then put everything back in place. In practice, this requires anticipation. You need to provide a cool place to store food, manage meltwater and wait until the walls are completely dry before turning the appliance back on. In short, it's the kind of task that you put off until the frost becomes really invasive.
This is where a simple trick can make the difference and considerably lighten this unglamorous routine.
