Empty the fridge and freezer completely: To defrost them, they must be empty; therefore, you will need to remove all the food from them. To ensure you don’t lose any food, we recommend planning the day you’ll defrost your fridge and freezer, thus avoiding overfilling them in the days leading up to the defrost. Also, get some freezer bags and freezer bags (the kind readily available at the supermarket): collect the food inside them so that it stays at the right temperature and doesn’t experience dangerous temperature fluctuations. In more serious cases, the ice may have “held” food packages or bottles hostage: in this case, you will need to wait until the defrosting process has begun to “free” them.
