It takes at least 2 - 3 hours to get completely cold if it's empty, up to 24 hours if it has food in it.But the food will still be kept cold enough during the original cooling process.ule of thumb is generally 48 hours in the refrigerator. It does not take more than 8 hours to properly marinate, but anything over 48 hours is too long.
Foods will stay safely cold 4 to 6 hours in your refrigerator. Hereâs the rule of thumb: If the temperature reaches above 40 degrees, throw out whatâs in your refrigerator and freezer. Your freezer will stay cold for two days if itâs full and one day if itâs half full. A full freezer that is not opened should stay cold for several days. If itâs not full, you can fill it with containers of water to freeze that will fill unused space.
