Cleaning outdoor HX coils
 

Saw this new product on youtube.
TriClean 2x - YouTube

I wonder if there are other cleaning products that will do the same job?
Something that's commonly available.?.

I'm looking at this kind of cleaner, because I can see a build-up of grime slowly starting to form, on my Sanyo coils.

I've seen people suds their coils up with Simple Green and rinse it down, it takes lots of rinsing through the coil to get the suds out completely. Usually people take the cover and fan off of conventional condensers. I'm not sure if it takes anything special as far a being sure everything can get rinsed out with a mini-split though.

I've never used Simple Green (that I can recall).. But I'll have to check it out.. Thanks..

Can you use a pressure washer to do this? Or will the high water velocity damage the fins?

Even my low pressure (electric) power washer (Karcher) folded the delicate fins on my window unit A/C in the garage. If you have the adjustable fan to zero tip you MIGHT be able to hit them with a low pressure washer adjusted to a wide fan spray, but I'd still be very careful.

That reminds me, I need to pull out my fin comb and straighten those fins. :rolleyes:

For my 3.5 ton central A/C, I simply use a garden hose as the A/C repairman suggested.

When I was building the new snow roof for my #2 Sanyo, my arm lightly touched
the fins and folded a bunch of them over. I hardly felt it.
Aluminum fins are like aluminum foil..
