Freezers that require manual defrosting should be defrosted at least once every 12 months.
Remove all foods and containers from the freezer and consign them to ice chests or other insulated containers. Unplug the freezer so there is no risk of electrocution, then open the freezer door.
Check the manufacturer's user manual to determine whether there are any risks involved with defrosting the freezer. If not, consider aiming a small fan at the opening of the freezer. This hastens the defrosting process. Alternatively, fill bowls or pans with boiling water, then place one on each shelf of the freezer.
Never leave a defrosting freezer unattended. Use towels or a shop vacuum to mop up the water as it melts. When the freezer is fully defrosted, clean it with a commercial cleaning product. Plug the freezer into its power source again, then wait until it has reached its ideal temperature before replacing food.
