I have the luxury of having two Tecumseh Condensing Units [< 1/2 HP] in my shop. They both suffer from an extensive case of "kitchen grease" contamination. I do realize, that they can be power washed, and if I am lucky enough to find a steam cleaner, and there is always the "elbow grease" method of using a cleaner such as Cal-Clean HD.
Does anyone have another alternative cleaning method that is really good....???
