Excess moisture in your refrigerator may seem like nothing more than a minor inconvenience that can be cleaned up with a towel. It can be caused by a plugged drain tube, a frozen defrost pan or some other defect in the drainage system. A recurring moisture problem needs to be properly dealt with to prevent the growth of mould and resulting unpleasant odours inside the refrigerator. Monitoring temperatures and installing a dehumidifier can help combat excess moisture in a refrigerator.
Clean out your refrigerator thoroughly and soak up any pools of water that may have formed.
Purchase a desiccant dehumidifier and place it in the refrigerator in order to absorb moisture (see resources). This device contains moisture-absorbing minerals and silica gel and will also serve to successfully remove odours that may have formed.
Store food in covered containers as a preventive measure against moisture build-up. If you leave an inch between all the containers and packets in your refrigerator, it will allow air to circulate and prevent a moisture build-up.
Observe the temperature of your refrigerator regularly by using a thermometer, ensuring it is between 1.11 and 4.44 degrees Celsius. This will help to prevent moisture from forming.
