Process of cleaning dehumidifier

Safety steps

When you plan to clean a dehumidifier then you should take some safety steps to avoid getting sick or electrocuted.

1. Put on gear.

You should put on rubber gloves and a dust mask to avoid inhaling dust and other airborne allergens as well as protecting your hands from dust, grime, chemical cleaners, and soap, etc.

2. Turn off and unplug.

Secondly, you should switch off and unplug the dehumidifier before starting to clean it to make it completely safe while wiping it from inside and outside.

3. Tank:

It is necessary to clean the tank of the dehumidifier where the water extracted from the air is collected to avoid the growth of mold.

  • Remove the tank and empty any water. Turn the tank over in a bathtub or sink to drain any water out from the bottom.
  • Wash with soapy water. You should detach the tank from the main unit to clean its interior with a mixture of hot water and mild soap.
  • Dry it with a towel before placing it to the side to clean the remainder of the dehumidifier parts.

Pro Tip: Attach a hose from the tank to a drain.

Since the dehumidifier will be constantly filling up with water to remove moisture from the air you will need to quickly dispose of the water or else risk mold growing.

If you don’t have a close drain nearby then you may have to empty the tank once a day.

4. Coils:

The evaporator coils on the back of the dehumidifier get very cold while the unit runs due to drawing in the moist air from the room to condense the air with the help of a fan. The condensation process will freeze if the air temperature is too cold.

  • Defrost the coils. Unplug the machine. Let it thaw for a couple of hours. Catch the dripping water and dispose of it in a drain or outside.

5. Filter:

You should remove the air filter of your dehumidifier and vacuum it to remove loose dirt and debris from it as it can be clogged up with the dust particles in the humid air.

Then you should rinse it with a mixture of cold water and mild soap to remove the grime and dust stuck on it. Then dry it carefully before replacing it.

6. With vinegar:

You can disinfect your dehumidifier by using the mixture of white vinegar and water in equal quantities. You can use this mixture to wash its tank and scrub its interior with a soft brush to avoid the growth of mold.

Before rinsing and drying the tank with a towel you should allow the vinegar mixture to stay in its tank for 30- 90 minutes according to its condition to disinfect it thoroughly.

7. Mold:

Mold in your dehumidifier can be cleaned effectively by cleaning its tank thoroughly by emptying it and cleaning it by using warm water and mild soap regularly. You should scrub its interior before rinsing it and drying it.

Cleaning FAQs

Can a dehumidifier kill mold?

No, but it does help prevent mold from growing in the first place.

Mold is a problem in many homes and it can be very frustrating to deal with.

There are two ways that you can reduce the chance of mold growth: prevention, or removing what has already grown on your home’s surfaces.

A dehumidifier will help keep relative humidity below 60%, which is often enough for eliminating most household molds without using chemicals such as bleach or vinegar (which may cause other problems).

What is the brown stuff in my dehumidifier?

Don’t let your dehumidifier get bogged down with grossness! It’s easy to avoid, though. First and foremost: keep it empty of water.

And if you’re wondering what those brown sludges are–they could be just about anything including mold spores which can cause respiratory disease; bacteria which may lead to infections; dirt from our shoes mixing into stagnant puddles left over after we emptied them days ago; etcetera ad infinitum until they’ve grown enough for us humans
