Generally, the temperature of the refrigerating chamber of a 12V DC Freezer https://www.chinafreezers.com/product/dc-freezer/
is between 0 and 7 degrees Celsius, while most bacteria can live very actively above 5 degrees Celsius. The refrigerating chamber that has not been cleaned for a long time will become a sealed container for bacteria to breed, which brings potential safety hazards to food health. Like direct-cooling freezers, we should develop the habit of regular cleaning, paying attention to the complete power cut before cleaning, using warm water or neutral detergent as much as possible, and at the same time paying attention to the application of electricity after completely drying.
It is a well-known knowledge that leftovers are put into the freezer after waiting for cooling. This is not only to save energy. If warm food is directly put into the freezer, it will change the indoor environment temperature in the freezer room. It will increase the frost burden due to condensation of water vapor. The increase in temperature will also provide conditions for mold growth. In addition to not putting warm food directly, small details such as separate storage of raw and cooked food and sealing of leftovers with plastic wrap also need your attention. They can prevent bacteria from cross-contamination in the freezer compartment.
