Today most freezer’s don’t require defrosting, Defrosting a freezer is a huge job and I remember helping my mum do this a lit when I was young. Modern freezers are great but they can use more energy than the manual defrost models. The auto defrost cycle sucks all the moisture out of frozen food and can affect food quality.
How to defrost
Empty out your freezer and have a really good sort through the foods. Food that you are keeping put into ice boxes
Make sure you turn off the power to the freezer before defrosting.
Leave the freezer door open for a while to melt the ice, this can take a while make sure you leave a few old towels on the floor to really soak up the water. If you haven’t got time to stand around and wait for the freezer to melt naturally place in a few pans filled up with boiling water to help speed up the ice melting.
Once all the ice has gone it’s a good idea to give the freezer case a really good clean, I find warm water and washing up liquid works really well. If you have nasty food smells mix bicarbonate of soda and water into a paste and run this all over and then leave for approx 30 minutes allow the bicarbonate to soak up the odours. Clean all the shelves and any draws the same way and ensure full dry before you put your freezer back together.
Once its all clean you can switch back on, leave a while for it chilly and then add the food back in nice and neatly and in order.
If you don’t have the hassle of having to defrost your freezer then give you freezer a good clean using warm soapy water and then dry really well before the food goes back.
