The first operation to do, when the fridge is a recent purchase, is that of emptying. If you intend to take time off for quite a long time, it is a good idea to completely empty the fridge and freezer and also unplug the power cord. If, on the other hand, the holiday is relatively short, we can avoid turning off the power but it is necessary to avoid keeping perishable food. In this case, the freezer can be left as it is, while in the fridge only products that have not expired can be left in sealed packages, such as preserves, jams, closed drinks, wine, beer. For everything else, it would be ideal to hand over to friends and relatives instead of throwing them away. We avoid waste.
The magic word is: cleaning! Thus, the second operation, after emptying, is cleaning to avoid going home and finding ourselves invaded by unpleasant smells. To clean the refrigerator you can buy special products in spray, which are very comfortable, but full of chemicals. If we like the idea of using natural products, we focus on products such as baking soda, lemon and white vinegar. With the baking soda a kind of pasta is prepared, obtained by mixing it with hot water, to pass with the sponge everywhere. With the vinegar go through all the compartments to eliminate the risk of unpleasant odours. Just pour a little on a rag and pass it carefully. The lemon can be mixed with baking soda. The smart advice? To enhance the deodorant action we can place a tray containing vinegar or ground coffee on the shelves, because both absorb odours. Effective and economical.
