What is a Dehumidifier Coil?
A dehumidifier coil is a heating element inside your dehumidifier that keeps the humidity level in your home low. The coil heats up water from the humidifier to create steam, which then comes out of the side of your dehumidifier and into the air.
The heat from this steam helps eliminate dampness by drying out the air in your home and removing moisture from it. This means that you don’t have to worry about mold or bacteria growing on surfaces that are moist, like bathroom tiles or kitchen counters.

How to Clean the Dehumidifier Coils?
There are various ways to clean the dehumidifier coils. The best way to clean the dehumidifier coils is by disassembling the dehumidifier and taking out the coils.
You can manually clean with various things like cleaning tablets, cleaning agents or solvents, and a lot of other things. Follow the guide to disassemble and clean the dehumidifier coils.
1. Drain the Dehumidifier
First thing first, you have to unplug the dehumidifier from the power source. If the dehumidifier is battery-powered, then make sure to power it off and, if possible, take out the battery. It will help you prevent the dehumidifier parts.
After disconnecting it from the power source, you have to drain the dehumidifier completely. If you are unable to drain the dehumidifier completely, then you can try using a dry cloth to drain the dehumidifier tank. Completely draining the dehumidifier will make it easy for you to clean it thoroughly.
2. Take the Dehumidifier apart.
After you have completely drained the dehumidifier, you need to disassemble it. You need to take out the back panel of the dehumidifier, to remove the coils from the dehumidifier.
You will need a screwdriver to remove the back panel of the machine. When you take the back panel apart from the dehumidifier, you can clean and remove other parts of the dehumidifier, which will make the cleaning effective.
You should clean the fan blades if your dehumidifier contains a fan. Moreover, you can also clean the filters, which require regular maintenance. Also, if possible and required, make sure you replace them.
3. Remove the Hose
When you are done removing the back panel and other parts, you have to disconnect the hose from the machine. The hose works as a duct when the dehumidifier is working.
The hose pushes the air toward the coil. Hence, it is necessary for you to remove the hose from the machine and clean it properly.
However, you should note that your dehumidifier will probably not have a hose, as it depends upon different brands, models, and their functioning.
4. Clean the Spots
After removing the hose and taking the back panel apart, you need to clean any spots or stains present on the unit. This will make sure that the unit looks accomplished. This is an optional step that you should follow while cleaning the dehumidifier coils.
The best way to clean the spots is by using a brush or scrubber, as it will easily clean the spots. Further, if you don’t have a regular cleaning brush, a toothbrush will get the job done.
5. Spray the Cleaning Solvent
When the spots and stains are cleaned, you have to spray the cleaning solvent or any detergent on the dehumidifier coils. The best cleaning solvent to clean the dehumidifier is a detergent or any other foaming agent which is readily available at our home.
Make sure to spray the detergent in the corners of the coils. After the spraying is done, leave it for a few seconds.
6. Cleaning the Coils
After leaving it for a few seconds or minutes, the dirt or dust will be easy to remove as it will not stick to the coil surface. You need to use a scrub or toothbrush to rub the coils. Make sure to rub every part of the coil and ensure you do not damage any vital piece of the coil.
7. Rinse the Coils
When the scrubbing is finished, rinse the coils with lukewarm water. Try to wash away all the residue, debris, and dirt. Hopefully, the dehumidifier will be cleaned in one go. However, if it is not completely cleaned in one go, then spray the detergent once more and leave it for a few seconds.
Then, scrub the coil with a brush, and rinse it with warm water. You can repeat the same steps until the coil is completely cleaned. However, there are chances that some dirt or residue will not come out, so you can use cleaning tablets, or other methods, which are listed below.
8. Let the Coil Dry
The coil should be dried with a dry sponge after being rinsed with warm water. To dry the coils, you can use any dry cloth.
After the coils have dried entirely, keep them in a dry environment for 30 minutes so that they can completely dry off the areas that you can’t dry with a sponge or cloth.

You can reinstall the dehumidifier coils when they have been cleaned and dried. Place the rear panel where it fits, and make sure all the screws are tight.
