Step 1: Unplug the unit from power: 

It should always be the first thing to do for any powered appliance. Choose a good place to clean the appliance because a lot of dirt has loosened. You will need a large piece of nylon paper or an old bed sheet that you no longer use.

Step 2: Getting to the Coils: 

Before you get to the coils, you need to do more cleaning. Since this post is just for coils, we’ll jump right into it. First, it’s best to start with a wipe-down of the exterior, covers, and all.

After removing surface dust and dirt, spray your foaming solution on the coils. If you’ve seen an auto mechanic use WD-40 rust remover on rusty discs, web cleaner works the same way. Spraying it loosens the hardened dust.

3. Use the brush again after spraying: 

If necessary, or if your coils had caked! Scrub vigorously with your brush. The dirt starts to fall off. However, be careful with the wings because you should not bend them.

4. Rinse the coils with lukewarm water: 

All build-up from the coils is gone. Now, this is the last step. Cover the engine so it does not get water, and clean the coils with warm water.
