The dehumidifier bucket is what catches all that water it sucks from the atmosphere. Depending on how much moisture is in the room the dehumidifier is in water and will be in the bucket for a period of time. Water creates lime-scale and a slimy feeling to any surface it stays on for too long.

To clean the dehumidifier bucket all you need to do is pour 1/4 cup vinegar into the bucket along with 3 tablespoons of dawn dish soap and wash It out with warm water. The vinegar will break down the limescale and the dawn dish soap will give it a nice smell and fresh feeling.

To clean the inside of the dehumidifier, you need to fill a cleaning bucket with water and pour some dawn dish soap into it. Use a microfiber cloth and wipe the inside as much as you can. If you can’t reach areas with your hand, use the compressed air in a can and blow out any dust or dirt. You can also use the end of a long spoon and push the cloth into the areas that are hard to reach.

Cleaning the outside of the dehumidifier is really easy. Use the same water you use to clean the inside and give the outside a proper wipe-down. Remember to wipe underneath and the back of the dehumidifier.

How Often Should You Clean A Dehumidifier?

A dehumidifier is what sucks out the moisture in the air around you in a place where there isn’t enough ventilation. For example in a basement, a dehumidifier will get full every 2 days while in a dining room it can take a week or more. It all depends on the area and moisture in the air. 

The more water a dehumidifier holes the more you will need to clean the bucket because water that stays in an area constantly will smell and make the area feel slimy. Even if you dump the bucket often. The filter on the dehumidifier as well needs to be clean every 2 months to allow it to suck in the moisture properly. With all that said if you leave your dehumidifier running all day, you need to clean it every 2 months if the area isn’t dusty to clog the filter.

This cleaning process can be used to clean almost any dehumidifier. The only difference is the location and how you take the filter out of the back of your dehumidifier. If you use your dehumidifier daily, you should give it a proper cleaning every 2-3 months to make your dehumidifier last as long as it should. The filter on the dehumidifier can be cleaned on a weekly basis so that the dehumidifier has maximum suction.
