3 Steps for Cleaning Dehumidifier Coils
Cleaning the coils does not take much. Get the following things:
- A small brush, moderately firm bristles
- An evaporator coil cleaner
- A vacuum hose and its brush attachment
- A pair of gloves
- Clean towels or rags
- Warm water
Step 1: Unplug the unit from power
This should always be the first thing to do for any powered appliance. Choose a good spot to clean the appliance because a lot of dirt will come loose and so you want a big nylon paper or an old bedsheet that you no longer use.
Step 2: To get to the coils
Before you get to the coils, you will need to do much more cleaning. Since this post is for the coils alone, we will not go into much detail.
First, it is good to start with a wipe down for the exterior, you know, the covers and all. These ones usually have no grease or grime.
Secondly, you need to detach the hose and clean it too. If yours is small and has a reservoir instead of a hose, well, you need to clean that too.
Remove the filters and clean them. If they are worn out, you can replace them with new ones.
You can use a damp cloth to clean the fan blades.
Step 3: Clean the coils
This is where the heart of the matter is. It is where the things we said you would need come in.
Use a soft brush to remove superficial dirt
First, you should use a brush with moderately soft bristles to scrub in an up and down motion. This will remove the superficial dust. You can buy such a brush on amazon.com.
However, the above step will remove just the superficial dust. If it has been some time before you cleaned the coils, you will have caked dirt and grime.
Not to worry though… it should be simple to remove!
Spray with foaming solvent for evaporators
After removing the superficial dust and dirt, spray your foaming solvent on the coils.
Here, you could use a product such as Web Coil Cleaner that you can buy on Amazon.com.
If you have ever seen an auto mechanic use WD-40 rust remover on rusty disks, the Web Cleaner works in the same way. Just spray it and the hardened grime starts to loosen up.
Use the brush again after spraying
If need be, or if your coils were really caked up!
Scrub with your brush firmly. The dirt will start falling off. However, be careful with the fins because you do not want to bend them.
Rinse the coils with warm water
All the buildup is gone from the coils. Now, this is the final step. Cover the motor so that it doesn’t get water and then clean the coils again with warm water.
To do this, you can soak a sponge in the water and squeeze it on the coils. That way, they get a good rinse and you don’t have to douse the coils with water.
An important tip
You can attach the brush tool to your vacuum hose and use it to scrub the coils. Scrub them in an up and down motion and do it gently so that you do not damage them.
That is the short process for how to clean dehumidifier coils. It is simple and straightforward. Besides, you don’t want to clean the rest of the appliance and leave the coils dirty, do you now?
