A Step-By-Step Process

1. Unplugging And Draining All The Water

Unplugging the dehumidifier should always be the first step when you're cleaning it. This not only prevents you from getting electrocuted but also prevents any unnecessary damage to your dehumidifier.

Then afterward, remove all the water from the dehumidifier. The dryer the unit is, the better. Failure to remove all the water could lead to moisture build-up and, inevitably, dirt and grime build-up in hard-to-reach areas.

Another benefit of drying the unit as much as possible before cleaning is that it exposes all of the build-ups so that you know which specific part needs a thorough cleaning. This makes your cleaning experience easier and will also lessen the cleaning time.

2. Disassembling The Dehumidifier

The coils are usually located at the back of the assembly behind a plastic panel. Depending on your dehumidifier brand, the plastic panel that covers the backside of your unit can be easily removed using a screwdriver.

Disassembling the unit also lets you see all the other parts that need cleaning. Parts like filters and fan blades also need regular cleaning and maintenance to work efficiently. Make sure to also replace the filters if they are already worn out.

3. Remove The Hose Attached

The hose functions as a channel that pushes the air over the coils when the dehumidifier is running. So make sure to detach it from the inside of the unit and clean it as well.

However, take note that not all dehumidifiers use a hose. Some brands use a reservoir instead. If yours have a reservoir instead of a hose, be sure to clean that thoroughly.

4. Removing Any Superficial Dirt

After you have already disassembled the unit and removed the coils, it's now time to start scrubbing. A brush is used for this specific purpose called a coil brush. We recommend you buy one as it makes the scrubbing part easier.

A regular toothbrush can also work if you don't have a coil brush at hand. Be sure to scrub up and down the coils to remove any superficial dirt that has built-up. This preliminary scrubbing makes it so that the following steps will become easier.

5. Spray Cleaning Agent

After you have removed any superficial dirt, you have to spray the coils with a cleaning agent next. For coils, the best cleaning agent to use is a foaming solvent. It can seep into the nooks and crannies and loosen up the dirt and grime.

If you have used or have seen anyone use a WD-40 to get rid of rust, then you know already how a foaming solvent works. They're identical in how they work. Once you have sprayed the coils, make sure to give it a few minutes to work its magic before scrubbing again.

6. Scrub, Scrub, & More Scrubbing

After spraying the coils with foaming solvent, you will see that all the heavy build-up of dirt and grime starts to loosen up. It's time to start scrubbing again. Make sure to scrub every portion of the coils but be careful not to damage other important components.

7. Rinsing Using Warm Water

After all that hard work you put into scrubbing the whole coils, it's now time to rinse all the dirt off. Because of the foaming solvent doing its magic and you doing all the hard scrubbing, all that dirt will be gone after rinsing.

If your coils still have some leftover mold, spray some bleach on the affected area and let it sit for a few minutes. Then afterward, rinse again thoroughly using warm water.

If you have one of those dehumidifier brands where the coils are rigidly attached to another electrical component, use a sponge when rinsing. Soak a sponge in warm water and squeeze it into the coils while gently avoiding the other critical components.

8. Drying The Coils

Now, this is the final step. After all that scrubbing and rinsing, it is finally time to dry your dehumidifier coils. Using a soft cloth, dry all the parts as much as possible. Get all the nooks and crannies that you scrubbed earlier.

Now we know that it's not unlikely that there will be some spots that won't be reached by a cloth alone. You can let it air dry for at least 30 minutes to get all the moisture out before reassembling the unit. Once air drying is done, do a quick check if all the parts are undamaged and make sure no dirt remains.

Finally, reassemble the dehumidifier and just plug it in. You have completed the cleaning of your coils. Congratulations!
