Simple GreenFoaming Coil Cleaner - Gallon, 128 Fl Oz (Pack of 1)

The coil cleaner works very well. The key is just read instruction on the bottle and to use it in a pump sprayer. I think people who are complaining that it's not for foaming did not do thatI've used it 3 years in a row in a does very good job. Per instructions, I delete 16oz of the concentrate to make 1/2 gal of solution - and that is enough for cleaning my medium sized Carrier A/C. So it is very cost effective and good value.In general, i like the brand and use their other specialized cleaners ( for example bicycle chain cleaner).

Simple Green is a brand that I trusted for cleaning and I don't this was any different. A friend is a HVAC contractor and said that while it wasn't quite as good as the commercial stuff he gets, it works very well

We love simple green. But be careful it is strong if mixed with other cleaners!! Let it sit and it does it's job.

I followed the directions and used a pressurized garden type pump to apply it. I was able to spray inside and out of my unit with only one gallon of the product reconstituted (1 qt product / 3 quarts water). There were a few bubbles but nothing I'd call foaming action. Regardless, the coils seemed much cleaner after rinsing them. Can't guarantee whether or not the same outcome could have been achieved using the hose alone but I'm satisfied with the end result either way.

Easy to use, I followed the instructions of 5 parts to 1. Sprayed exterior unit heavily and scrubbed coil….cleaner removed grime and oxidation.Washed of with water house. A/c exterior unit cooling more efficiently now.

Having used Simple Green cleaner I expected Simple Green Foaming Coil Cleaner to be as good well its not. I mixed 3qt - 1qt sprayed it on with my stihl back pack sprayer I got some bubbles but no foam coil was nowhere close to clean. I tried a second time at 2.5qt - 1.5qt I got more bubbles no foam coil is not as clean as I would like, I've gotten it cleaner with 1 try with other products I ran out of daylight. Tomorrow I will mix 1.5 - 1.5 50/50 and see what type of bubbles I get. Oh the stuff stinks, I will not buy again.

Easy to use

Worked great and much cheaper than prepackaged mini split/condenser cleaner.I cleaned 3 mini splits and 3 condensers and have plenty left for next year.Will I buy again? Yes!
