Remove any fridge magnets on the door.
Set the fridge dial to zero, and switch off the mains supply.
Remove all the contents - wrap frozen food in a couple of clean carrier bags.
Remove the shelves.
Move the refridgerator to the middle of the kitchen.
Place a couple of bowls of boiled water in the ice box - use a couple of plastic lids under the bowls.
While the steam from the bowls melts the ice, clean the inside of the fridge using a mild detergent solution, and the shelves, including the tray that slides under the ice box if your fridge has one.
Only use the same cloth for cleaning the fridge, don't use any other cloth that has been used for cleaning other surfaces.
Using a piece of plastic, push the melting ice off from the ice box.
When finished, tilt the fridge slightly to run off any remaining melting ice.
Use paper kitchen towels to wipe dry all the surfaces.
Look out for any drips, and tilt the fridge again to run off any remaining melt water, and wipe again any areas that are still wet.
Clean the outside of the fridge, and the elements at the back, removing any dust.
When ready, move the fridge back to its normal place, switch on the mains plug, and set the fridge to a medium setting - not too high. Usually around 2 or 3 should be sufficient.
Place frozen food in the ice box first, then everything else on the shelves and the door shelves - eggs should be kept in their box on a main shelf.
Remove any water from the floor.
