Simple Green Foaming Coil Cleaner - 32 Fl Oz

This coil cleaner exceeded my expectations. I used it on my home AC unit that hadn’t been cleaned in quite a while, and the amount of dirt and grime it removed was impressive. The foaming action really helps lift buildup from the coils, and it was easy to rinse away afterward. What I liked most is that it’s simple to use. Just spray it on, let it sit for a few minutes, and rinse if needed. The foam expands nicely and gets into the tight spaces between the fins. I noticed better airflow and the system seemed to cool more efficiently after cleaning. Another plus is that the smell isn’t overpowering like some harsh chemical cleaners. It still feels strong enough to do the job without being overly harsh or messy. The cans lasted longer than I expected, and the spray pattern was consistent all the way through. If you’re trying to maintain your HVAC system or improve efficiency without paying for a service call, this is a great product to keep on hand. Definitely something I’ll purchase again.

I’ll confess…. like so many others, I’ve never given a thought about cleaning the coils on my central air conditioner. Then I saw a YouTube video and figured why not? I ordered this product, and today (a couple of days before we hit a stretch of 80’s this week) I went out and did it. I noticed last summer that the performance had gone down a little - especially on the hottest days. Taking off the outer jacket panels was simple enough. I was careful not to lose any screws AND to not strip them out when re-tightening them. I was a little surprised at all the grass and dirt inside, but what else could I expect after 15 years of never cleaning the coils. I gently brushed off the grass, leaves and dirt, and then sprayed the coils down inside and out and let it sit for 5 minutes. I then rinsed them off and repeated the process. A LOT of dirt was running out with the water after the first application, and much less the second time. It looked a LOT cleaner. Not perfect, but clean, as the aluminum fins will oxidize regardless. I put the jacket back together (no extra or stripped screws), turned on the power and set my thermostat for 60 degrees to make sure it still worked. It did! Of course the air outside was in the low 60’s so I can’t quantify how much of a change it made, but I figured it was the equivalent of changing a clogged filter that hadn’t been changed in 15 years. If I called a local HVAC service company to do the job I’ll bet they would’ve charged me a minimum of $150 to do the job, so I’m liking the 90% cost reduction by doing it myself. I trust my HVAC/boiler/fuel oil guy implicitly to be fair and do a good job, but this took less than an hour and there was little risk of me damaging anything. I doubt I’ll be doing it religiously every year, but I’ll definitely be keeping a closer eye on it.

[60+ female] This was my first time of cleaning the outside blower of my H-Vac unit. After checking prices and brands at local stores, I decided to order these instead. More for the money and good reviews also helped deciding on this brand. I watched YouTube videos of people using it, then went to work on it. I was very happy with this product and how well it cleaned all of the gunk off the coils and surface of the blower. And a huge plus was it was much easier than I had expected with this product doing such a great job. I did flush it off with the water hose on a gentle setting to remove the product after letting it sit for15 Minutes. Also, it only took ONE can, and honestly, I expected to have to use all three cans. Being that it had not been cleaned in years and this worked so well, it only took the ONE can. I suggest this Simple Green to everyone for their H-vacs.

This is a pretty decent product. My main issue is that the foaming when spraying it even with a pump sprayer application is not that great. The product does spray well and it does wash off well but foaming is at a minimum for a product of this nature. I switch to a slightly higher concentration hoping that the spray would be better when spring the coil and it was not. The effectiveness of a product of this nature is reduced when it's not foaming and raising the dirt and debris off the coil.

When mixed according to directions(3-1) this stuff worked well above my expectations. I’ve tried to clean Trane spine fin condensers and have always come up wanting. When used a foam pressure sprayer it works so well it only took a gentle spray to wash out the gunk and really get a clean coil. I wish I had known about this stuff when I was doing these coils every day, it would have been a game changer. I’ve had my run-ins with watery limp foam. This foam was thick and clung to the coils allowing it to really get the gunk out. I will definitely be buying more of this. Thank

This stuff works great. I use it to clean stainless gun parts and it’s amazing. FYI- this particular version of Simple Green is not green. It clear with a slight yellow tint. And it doesn’t have the fragrance I’m used to. Still seems to work the same as usual though.

works as described Had no issue with spraying foam after shaking very well & used can upright spraying side to side. Use eye protection a mask and gloves to be safe. Turned off power to unit while using product & had opened unit to vacuum out debris at inner base. I sprayed through outside fins did not need to remove sides of A/C condenser as my unit wasn’t that dirty with caked on debris. left it on for an hour foam had disappeared and no damage to exterior of A/C paint finish. I hosed off using shower spray to not have forceful water bending coils. could see water coming off was dirty as it ran down sides. . after done could see through coils I purchased 3 pack of cleaner but one can was enough to do my 4 ton unit all sides on outer unit. - inside wasn’t needed this time. would have needed two cans if did inner coils. shared can left with others. would purchase two to ensure have enough Happy with results

Works well but, The button on top to start the spray is the very old and very small design. It feels poor on your finger and spins around if your not carful.

Excellent. PAY ATTENTION: this product is concentrated, so mixed with 2/3 water and 1/3 of simple green, you will get 3 gallons final product. This is a lot. I did use around 300 ml for one air conditioner so still remaining around 3400 ml in the gallon 😳😁

Funciona muy bien para limpiar los serpentines tanto del equipo de afuera como el de adentro

Works great for cleaning my AC coil. Added some cleaning solution into a small pressure sprayer and water pumped it up and hosed down the coil, used water hose with nozzle cleaned it all up, ready for the season, do it again next year.

Muy util para limpiar los serpentines metálicos de una unidad de minisplit. Es importante notar que el producto debe diluirse con agua, y se debe utilizar un atomizador que tenga una bomba de presión.

The foam cleaner does a good job and cleans surfaces effectively. I was happy with the results and it was easy to use. The only reason I'm giving it 3 stars is because I feel the price is a bit high for the amount you get. If it were more affordable, I would rate it higher.
