A/C Condenser coil cleaner

[theoldwizard1]

Neighbors step-son does commercial A/C. In passing, he said the quickest way to improve the performance of you A/C is clean it with condenser coil cleaner.

Grainger has dozens listed. Several different brands on eBay.

Any recommendations from you A/C guys ?

I just keep my condenser clean by washing it off with a hose and keeping debris from around it

Water and lots of it, garden hose pressure, do NOT use a power washer.

Chemical cleaning a residential condenser is very rarely needed and on some newer units with plate/fin construction can be harmful.

+1, Unless you have allot of scale buildup on your coil I always use water. Pull your service dissconect fuse or breaker, and direct the water spray from a high pressure hose nozzel, going from side to side, starting at the top, and working your way down. Direct the spary downwards, as to keep as much water out of the control box as possible. Let it sit a while, and fire it up. I have seen what looks like chocolate milk roll out of the bottom, especially if the unit sits in or around dirt.

IIRC, commercial coil cleaner is sodium hydroxide. Serious stuff, use only when needed. It'll eat your skin off.

I have white corrosion build up on my condensor coil from salt that was used on the roof to melt ice dams a couple of years ago. The condensor looks like heck but works okay. I've tried spraying stuff like CLR on it and rinsing it off a few mins later (before the aluminum fins could be substantially impacted), and it helped only a little.

I will try Simple Green next. Any other ideas to remove some of the salt and caked on corrosion?

FWIW, Grainger has a 1 gal concentrate of Triple D for $13. Dilute that 1:6 with water.
