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 recently used the Simple Green Foaming Coil Cleaner 20oz to service my home’s HVAC unit, and I am beyond impressed. If you've been putting off cleaning your coils because it seems like a chore, this is the solution you need. Why It’s a Must-Have: Powerful Clinging Foam: The foam really stays where you spray it. It lifts dirt, dust, and grease out of the fins effectively, reaching deep into the unit where a brush or cloth simply can't go. Convenient Design: The ability to spray upside down is a total game-changer. It allowed me to get into the tightest angles of the evaporator core without the can sputtering or losing pressure. Professional Results: After one application and a quick rinse, my coils looked brand new. I’ve noticed a definite improvement in my unit's efficiency and air cooling speed since the cleaning. Safe and Non-Toxic: I love that this formula is self-rinsing on condensate coils and has a very mild scent. It’s much more pleasant to work with than the harsh, caustic chemicals found in other industrial cleaners. Final Verdict: This is hands-down the best DIY maintenance product I've bought this year. It saved me a $150 service call and did a professional-grade job in about 20 minutes. Highly recommended!

[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.

I read reviews and many said the cleaner didn't foam much. My AC units weren't extremely dirty so for the price I felt I couldn't go wrong with this product. I mixed it 1 qt cleaner to 3 qts of water in my pump up sprayer with a wand. I shook it up real good and pumped the sprayer up for the best pressure. There wasn't much foam but there was some. I sprayed it on heavy soaking down the coils heavily. After letting it sit I hosed it all off and the coils shined nicely. The 1 gal in my sprayer was enough to easily do my 2 outdoor condenser/compressor units. It would have been nicer if it foamed when applied like the aerosol cans do but for the price the gallon will last me a few years doing the outdoor units.

This foaming spray work great use it to clean my air conditioner in my home it did it cleaned it out good I recommend it

First time cleaning my AC unit. Product worked great! Sprayed on, waited 10 minutes, and rinsed with shower setting on my hose. Rinse from inside out. Could were very, very dirty and looked brand new when done. See pictures.

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.

I followed the mixing instructions and pumped up my sprayer. Never saw ANY foam. Sprayed it on my AC coils and let sit for a few minutes. Maybe cleaned a little but did not do like other coil cleaners do. Disappointed in Simple Green.

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.
