How do you clean a brand new refrigerator before its initial use?

Remove all food and keep in a cold place. Best to do this when your fridge/freezer is nearly empty. Switch off at socket and leave the doors open to let the freezer defrost. You sometimes get a plastic scraper with fridge/freezers to help you scrape off the ice. If you don't have one try the one you get to scrape your windscreen on your car just don't use anything metal as you will scrape the lining - not good. Once defrosted, mop up any water and close freezer door. For the fridge, a lot of the drawers, door compartements and shelfs will come out and you can wash these in warm soapy water. You can wash out the inside of the fridge with a cloth and warm soapy water as well. My tip though is to use toothpaste. Use it like you would use a cream cleanser - put a little bit on a damp cloth and rub over the surfaces. Clean off with a clean damp cloth. Not only will it clean but it gets rid of any bad odours too!! Once it is all clean, close doors and switch back on. Good luck.
