What should we do if the glass doors of a refrigerator or a freezer get foggy ?

 It will seriously affected the items being clearly to showed to  the customers if there is fog when the refrigerator or a freezer unit are on work stage. Especially in places like supermarkets, if put items in  a refrigerated unit with a layer of fog on its surface, so originally the customers could not see the items display in it clearly. The customer would like to open the freezer or the cold storage cabinet . over time, the door of the freezer is easy to be damaged for opening and closing so frequently , and it will no doubt increasing the power consumption of the refrigerated unit.

    If so, we can take a piece of dry cloth to wipe it off . We can solve this problem by ourselves in a short time, as there is fog on the  freezer door because the different temperature of inner and outer of the glass or non-uniform refrigeration effect. So try to keep the same temperature both inside and outside. But of course, this is not the best way.

    In order to avoid such cases, you can buy the air-filled freezers.This type of cold storage cabinet can avoid this problem, because it blows out the wind in all directions  with uniform temperature.
