I've had DSS problems as long as I can remember. Had a new Carrier 2 speed installed a little less than 2 years ago... still has strange odor, definitely from the coil. Decided to take some close-up pictures of the coil. Full of white residue of some sort (probably causing the DSS). Has a 5" Carrier Merv-10 filter. My guess is oxidation? Here's some pictures:

Anyway to clean it? Please let me know what you think.
