Essential ValuesCoil Cleaner for AC Unit (Gallon) | AC Coil Cleaner That is Non Foam Formula for Condenser Coils - Heavy Duty Professional Grade & For Commercial & Residential Air Conditioner

Works great Mixed per instruction washed off clean.

Used this for first time this weekend on heat pump pool heater. There had been at least two years of build up, greenish dark gunk. I first used a small vacuum with medium nylon brush attachment to remove this season's cotton wood (probably last season's too). Directions were to create a 7:1 ratio water:product. I was more like 3:1. I really had low expectations. I sprayed on with battery sprayer, two coats. That was much easier than hand pump would have been. Might have sprayed a few pints total. Let it sit for a full 10 mins. Garden hose sprayed it off. Top to bottom rise until all suds were gone. I could not believe how clean the fins were. All of the gunk was gone. Only spots it missed were where the outer cage had blocked the spray or rinse. 99%. They looked lime new.

Used as directed and it cleaned my unit up nicely

Quality product that worked better then I expected it to and smelled really nice! I put it in a spray bottle and sprayed the coils, let it sit for about 10 minutes, then rinsed off. There were foamy dishwater like bubbles that came off and the coils were a bright shiny silver color again. It had a minty smell that was surprisingly pleasant. Was very easy to use and cleaned up really good.

I have used other products like this from home improvement stores before. This cleaner is awsome and best I have used.

Works great. Great value

It isn’t as good as other cleaners I’ve used for AC coils. It does a great job as a deck cleaner.

I previously used a spray foam, and it was ok but did not clean that well. After using this product, the fins were back to their original color with no dirt remaining.
