The biggest freezer mistake people make is not keeping the freezer set to the proper temperature. If it’s too warm in there you’ll get transferring odors, freezer burn, and foul tasting food. Invest in a freezer thermometer and make sure it says an icy zero degrees in there.
All that opening and closing of the door can cause shifts in temperature. For this reason be sure to place foods in the appropriate spot. If you aren’t going to be reaching for it for a while, keep it in the back of the freezer. Frequently used items can go closer to the front or in the door.
Pointers for keeping your freezer spic and span include: wiping down shelving with a damp rag to keep it free of dust and debris and placing a box of baking soda in every 3 months to help absorb odors. See ice building up? If so, it’s time to defrost! Check the manufacturers directions for details on how.
