We start with a vacuum cleaner [shop wet-vac best], then we spray them with Krud Kutter
[water based, non-corrosive...] wait a few minutes, and vacuum again [we use a shop-vac that can tolerate liquids.] Get the vacuum nozzle right on the fins [carefully] so it is sucking hard between the fins. [i.e., the soft brush attachment isn't much good for this...]
If they still need cleaning, more Krud Kutter, and a tooth brush to work
it loose. You may also be able to spray it with water
from a hose - depending upon your set-up.
Worse case you can buy air conditioner 'cleaner' in auto parts
stores and that works pretty well too... Read the labels and get something compatible with your system and situation...
Do you have a way of measuring your refrigeration efficiency? We installed simple analog hour meters. Very useful...
