you guys possess! I just let gunk accumulate until it evolves into a
lifeform. I didn't realize that there was an alternative.

For cleaning aluminum filters, has anyone tried steam cleaning? I have
tried steam cleaning on greasy oven pans (stainless and enamel) and it
works like a charm, though you want to be careful where you let the
condensed steam drip - it carries the oil and grease with it.

chlorinated detergents
Yes... I think chlorinated mainly for those compound's sanitization
properties... but unless one is trying to sanitize those old filters
(wouldn't hurt: right?)... I'm skeptical that chlorinated compounds add
much to the cleaning ability of such detergents, relative to detergents
containing phosphates. (I don't know that there are any modern, for sale,
formulated detergents that perform as well as the discontinued/banned
phosphated ones.)
To clean some really dirty, and old, 500 aluminum filters, I tried a lot
of different solvents, and cleaners... and finally I settled on TSP. The
difference, as Dr. Beaker would say, was most satisfactory.
