Zenlifer WEB WCOIL19 19 oz Coil Cleaner, 19 Fl Oz (Pack of 1)

A YouTube video recommended this product, and he was right it dissolves any gunk and pollen that collects on your A/C condense. Make sure to cut the power to your A/C unit. The easiest way I think is to remove the top lid of your unit that houses the fan. Should be a hand full of screws and then it can be removed. This will give you access to the inside of the unit. Remove any debris and gunk from the bottom of the unit. Since the bottom should have some drain holes (this will be handy to have unclogged later on)Now all you have to do is spray the outside and inside of your condenser (radiator looking thing) This can should be plenty to get good coverage inside and out of 1 unit. Let it sit for 5-10 minutes and go ahead and rinse your condenser thoroughly. All the dirt will wash down to the bottom of the pan and if the holes are unclogged can just seep out the bottom.Make sure not to use a pressure washer since the fins on a condenser can be easily bent. My garden hose was fine to rinse it all out.*wear latex or equivalent gloves and eye protection when you are spraying this cleaner!

Spray nozzle doesn’t foam. It shoots a straight stream causing you to waste spray. Not nearly enough for a 3ton unit. Waste of money

I looked at a few coil cleaners on amazon and settled on this one because it was the cheapest (At $6.95/ea).I don't think my AC units have ever been cleaned since they were installed in 2015, so when I took off the outside guards I saw the pollen mixed with cottonwood from the trees I knew I had a mess on my hands!.Ignore the reviews that say the "cleaner did nothing" or "doesn't work". No cleaning agent will ever get your unit like brand new. That's just now how it works.I recommend1) Remove gaurds (leaving them on the unit is practically useless2) Use a shopvac or strong suction vacuum to remove material stuck on coils. Try to avoid pushing the fins over. They are there to radiate heat and when they are all smashed (or gummed up) they don't work as efficiently.3) Spray coil cleaner on fins (inside and out). A 19oz will get you about 75% of the way there. Skip the interior fins if you want to be sure you hit eveything on the outside.4) Spray clean with a nozzle attachment on your garden hose. This by far the most effective part of cleaning the coils. If you want you can rinse before step 3, perform step 3, then rinse in step 4. Your call.

Seemed a little small for our large unit. But worked very well.

To properly clean your AC condenser coils, you should first determine if you have a single or double coil condenser. You can do this by first removing power with the electrical safety lockout, removing the top cover and examining the top of the coil/fin assembly now visible from the top. If you have a double-coil condenser, it will be very apparent when looking at the top. There will be two rows of copper tubing, one visible from the outside and the other clearly visible on the inside. Both should be cleaned with the spray cleaner, but you may have only enough to spray the outside with one can. Buy two, just in case.

Will it sprayed out all crappy. So then I shook it and shook it until my arm fell off. And it just still straight out sprayed out crappy and never did spray it out foamed up... Then also I looked all over the can and where the hell is the instructions and say how long to leave it on >Huh seems weird. There was no instruction to say for half an hour there was no instruction at all to say how long...

Using this coil cleaner was easy to use. I bought 3 cans (I have 2 a/c units). Sure enough, one clogged or would not spray. Otherwise, the other 2 did a good job. You'll do a better job if you can spray into the inside of the coils. You must remember to rinse the cleaner from coils after about 15 minutes. Make sure your A/C unit of off when you use spray this and rinse the coils. If not, you may be injured by the compressor fan.

I bought this item because a youtube hvac man recommended it. After taking my large Goodman heatpump apart and that is a lot of work as it goes together like a jigsaw puzzle. I get my fresh can of Web Wcoil 19 out to empty the can onto the nasty coil after cleaning everything out with my shop-vac and after spraying about 2 minutes it runs out of pressure. I had shaken it a lot before I started and I shook it as I was spraying, but it invariably would turn to foam as it came out and then run out of propellent, I just drizzled it on the top of the coil and used it as best I could. I jabbed the can with an icepick at the bottom and hoped it would spew out so I could coat the coil lower down but it wouldn't spray out and just dribbled out. I ended up cutting it open and pouring it. A step that should have taken me about 10 minutes took an hour.
