Simple Green Foaming Coil & Condenser Cleaner, 32 Fl Oz, HVAC & AC Cleaner

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!

Foams wide soft spray nicely. Sprayed from 2 angles to get uniform due to large grid metals. Heavy spray...let set 3-4 minutes. Dust, rain soaked dirt and most seed fluffs lift off. Then put on hose at a SLOW soft flow and washed from top to bottom. No hard spray to push stuff back in deeper...let the foam lift off the stuff. Gently rinsed away 15 years of collected dust etc. Some heavy leaves twigs left at the very bottom...use needle nose to remove. THE ALUM INUM COILS LOOK BRITE AND NEW. NO VISIBLE DIRT as seen from outside.....majority of paths opened up. I ran the water slow and softly until the dusty dirt mud quit flowing. HAD to do the bad side a 2nd spray...but plenty in my one can to do the unit 2X if needed. THANK YOU SIMPLE GREEN. Can goes VERY FAR. Will do about every 2 years now I have spare cans of spray. Should have done before and after pic...but its good.

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.

If your refrigerator coils are dirty...this stuff will clean every bit of dust and hair off the coils. You just unplug your refrigerator and spray front and back. It was astonishing how well it cleaned. And no toxic odets ir residues. Great product.

So Easy to use and works without any scrubbing. The product foams up well and has a light scent which dissipates after running the AC for a short time. I ordered three cans for my three AC’s but one would have been sufficient for all three.

I have 4 mini splits and live in the country. Definitely need to clean the compressors every 3 weeks. This stuff works great . I let it sit for 10 min than wash off. Gets off all the dirt and crud.

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.
