What is the best way to clean an Electronic Air filter
I'm sure this has been discussed before but I wanted peoples opinions on the best way to clean the electronic air filter cartridges. I have a Honeywell 20x20 F series. I put them the dishwasher without detergent and it seems to do a mediocre job. I'm hesitant to use detergent because sodium hydroxide eats aluminum.
Do these contain aluminum or just stainless?
Is there something else to use instead of detergent, like maybe vinegar?
Am I just being conserative and I really should just use a regular load of detergent?
