1, wipe the surface of the orange with a damp cloth and dry it. Remember, when wiping oranges, don't squeeze or damage the orange peel. Then put it in a plastic bag, seal it and put it in a cold place, neither too hot nor too cold, as long as you know it won't freeze. In this way, the freshness of oranges can be kept about 1 month.

2. Find some baking soda (not too much), dissolve it in water, wash the oranges one by one with soda water, let the oranges dry naturally, and let the soda water form a protective film outside the oranges. Then, put them in plastic bags. Finally, seal the bag, be sure to seal it. Don't let air into the bag. In this way, the shelf life of oranges will be extended for a long time, and there will be no problem for three months.

3. Another method is to clean the oranges, dry them, wrap them with plastic wrap to prevent breathing, and then put them in the cool place of the refrigerator for up to 4 months.

I hope it helps you!
