I use dehumidifiers in my home every day and it’s shocking how quickly dirt builds up on the vents. But that’s just the dirt I can see, and there’s a lot more dust and debris building up inside the appliance.
Over time, this dirt can stop a dehumidifier from running. That’s why I make sure I properly clean my dehumidifier regularly to keep it working as it should.
In this guide, I’ll show you how to clean every part of your dehumidifier, and tell you the signs to look out for so you know when your appliance is in need of some TLC.
Cleaning Tools You Need To Clean A Dehumidifier
Pair Of Rubber Gloves
Rubber gloves protect your hands from the cleaning solution and bacteria that may be lurking inside your machine. This stops your skin from transferring or absorbing harmful things.
Dust Mask
A dust mask ensures that any pet dander, dirt, or bacteria that enter the air does not get into your airways and damage your health.
Towels, Rags, Wire Brushes, & Small Toothbrushes
Cleaning supplies like towels, rags, and brushes help you remove any pollutants from your machine and thoroughly clean the dehumidifier’s parts. I like to use a toothbrush to clean some of the harder-to-reach areas within the dehumidifier.
Soap & Household Cleaning Agents
Soap and other cleaning agents eliminate bacteria and ensure that your dehumidifier is clean and safe to use year-round.
Dry-Wet Vacuum Cleaner
A dry-wet vacuum cleaner ensures that you remove dirt and dust from all the nooks and crannies of your dehumidifier, cleaning and drying at the same time.
How to Easily Clean Your Dehumidifier
To properly clean a dehumidifier, I recommend washing each individual component separately using soap, water, or distilled white vinegar.
This cleaning process will eliminate all the dust, mold spores, bacteria, and remaining dirt so that your dehumidifier functions properly.
Not all dehumidifier components can be removed, and it depends on the size and type of dehumidifier you have. If you can’t remove the individual components then I recommend cleaning the dehumidifier more frequently if possible.
- Turn off and unplug your dehumidifier.
- Put on your protective gear and thoroughly ventilate the area.
- Disassemble your dehumidifier according to manual instructions.
- Empty and clean your reservoir water bucket.
Empty your reservoir into the sink and rinse it carefully with warm water. Fill the sink with hot water and dish soap and let it soak for a few minutes. Then, use a soft cloth to clean your reservoir and a soft-bristled brush to scrub the corners. Leave the water bucket to dry. - Remove and clean or replace your filter according to manual instructions.
- Clean the coils and internal parts.
Use a spray detergent or spray bottle filled with a cleaning agent to cover the coils and leave them to soak for a couple of minutes. Give them a scrub with a cleaning toothbrush. Cover the motor to avoid water damage, and pour warm water over the parts. Use a dry cloth to pat it dry. - Wipe and lubricate the blades with a damp cloth and 3-4 drops of oil.
- Dust and vacuum the rest.
- Once all the parts are completely clean and dry, put the dehumidifier back together according to manual instructions.
- Wipe down the external surfaces with a damp cloth and mild liquid soap.
- Run the machine, keeping an eye out for condensation on the coils.
If you do find condensation on your coils, I would recommend calling in a professional to provide restoration services and fix your dehumidifier. It may also be a sign that you need to replace it altogether.
Dehumidifier Components Which You Need To Clean
Air Filter
A dehumidifier air filter is designed to remove any air pollutants as the dehumidifier is pulling moisture and air in.
Coils
These cold coils cool the air before it is reheated and emitted back into your home. These are one of the most important parts of the dehumidifier and need to be maintained properly.
Bucket Filter
Some dehumidifiers come with a second filter in their reservoir bucket. This is tiny bucket filter is used to help improve the dehumidifying process.
Exterior surfaces
The exterior surfaces and outer shell of your dehumidifier help protect its parts and keep them in place in an aesthetically pleasing way.
Reservoir / Reservoir Bucket
The reservoir bucket holds the water that is removed from your air during the dehumidifying process. These can quickly become a breeding ground for bacteria, pollutants, and dust mites because of the stagnant water.
How To Clean Your Dehumidifier With Vinegar
Yes, you can clean a dehumidifier really effectively with white vinegar instead of dish soap or detergent. White vinegar is an effective disinfectant that helps to dissolve bacteria and mold build-up [1].
I mix 1 part vinegar with 1 part water to create my own cleaning solution that’s much cheaper than other chemical cleaning products.

5 Clear Signs That Your Dehumidifier Needs Cleaning
I often find that in the summer, the dehumidifier vents become noticeably dirty – which is obviously a clear sign that you need to clean the appliance.
However, even if your dehumidifier seems clean on the outside, you may be unaware of a potential problem growing internally.
The signs that you need to clean your dehumidifier include:
- Louder than usual noises from your dehumidifier while it is running. This is usually because of a blocked air filter.
- Increased allergy symptoms while in use, usually because your dehumidifier bucket or air filter is dirty.
- A musty smell coming from the machine when in use.
- Black spots or mold can be seen on the inside.
- It has been over a month since you cleaned it. I have a strict cleaning routine and if it’s been too long, it’s definitely time to clean!
How Often Should You Clean Your Dehumidifier?
You should clean a dehumidifier every 2-3 weeks. Regularly cleaning the dehumidifier is essential to keep it running properly and the more you use it, the more frequently you should clean it.
I use my dehumidifier more in summer, so I clean the outside every week and clean the internal components every 2 weeks.
In winter, there’s less humidity so I only clean the inside every 3-4 weeks. Make sure you empty your dehumidifier tank daily alongside regular cleaning.
If you leave the tank full, it will stop the dehumidifier from being able to draw moisture from the air, allow bacteria, dust, and dirt to build up in the reservoir, and could even cause water damage.
What Happens If You Don’t Clean Your Dehumidifier?
If you don’t clean a dehumidifier properly, then it won’t function properly and it could harm your health and well-being.
Dust, bacteria, pet dander, dirt, and potentially harmful microorganisms all accumulate inside your dehumidifier tank and air filter, and if they aren’t cleaned out, then the dehumidifier will start to release these into your home.
Your dehumidifier may also struggle to run properly if it isn’t cleaned regularly.
This can leave you with excess moisture in your home and may cause your dehumidifier to draw more power to function, increasing your electricity bill.
In extreme cases, the dehumidifier can even stop working completely. This just isn’t an option for me because I live in a very humid area so I have a strict cleaning schedule to keep the device running.

The brown stuff in your dehumidifier is usually dirt and mold that have accumulated on the inside. This occurs because the moisture is pulled in from the air. Regular cleaning and maintenance will keep it out of your dehumidifier.
Conclusion
Dehumidifiers are excellent appliances to have in your home which improve your quality of life.
The dehumidifiers in my home have been running flawlessly for over 5 years because I keep to a strict cleaning schedule. This has not only allowed me to maintain the indoor humidity levels effectively but also saved me from having to spend money on repair work on replacements.
