Product Description

An heavy duty foam detergent coil cleaner in the convenience of an aerosol can. For use on most coils such as window air conditioners, central HVAC units, auto radiators, condenser and evaporator coils, metal filters, fan blades and more. Water based. This product can be sprayed in any position while the blasting stream easily reaches into tight areas. The aggressive detergent quickly and easily liquefies dirt, grease, oil or other residue and deposits. Fortified with corrosion inhibitors to prevent metal degradation, Will not harm drain pans, plastic or other materials in and around the area. The clinging foam is completely self-rinsing on condensate producing coils. Simply spray on and condensation generated will wash away the material. The pleasant citrus fragrance helps leave the area smell cleaned and deodorized. Contains no CFCs, chlorinated or fluorinated solvents. Cleaning coils increases efficiency and saves money. Directions: Turn off or disconnect power to unit being serviced. Shake well. Remove cap and point toward surface to be cleaned. Avoid spraying on electrical wires or connections. Thoroughly saturate the targeted area with product. With this self-rinsing formula, the foam will break and condensation accumulation will completely rinse the emulsified material. Scrubbing cap is great for removing large, imbedded pieces of debris. You may wipe clean or rinse with water if desired or if using on non-condensation producing coils. For extremely stubborn or heavy deposits, repeat application may be necessary. Turn on or return power to unit.

"...The only bad part is after you use it for a while the foam starts running down the can of your hand. But overall it's a nice non-rinse cleaner." Read more

No more Mildew smell, messy to use

Reviewed in the United States on July 26, 2023

Scent: LemonSize: 1.19 Pound (Pack of 1)Verified Purchase

Does not dissolve dirt or dust, etc. It lifts it up off the contaminated area and bubbles it to the surface...u still need to wipe or rinse to get all the dirt off. I had been spraying a bleach solution prior to using this.

This worked MUCH better. The fin scrubber was good to use, but more for larger units unless you take the whole face off. I used this to clean the inside of my 12000btu unit. Took the entire bottle, 4 treatments one right after the other to get this ac fairly clean.

Very messy high pressure spray. So stand back a few feet when using or u will get it all over urself. Put a towel down under the unit and plan on using paper towels to wipe away the grime after each foam treatment.

Overall, worth it and will use it again in the future. Mild smell, but dissipates after 15min of turning on the unit. Again, this was after 4 full foam sprays into the fins and coils and into the vents.

Really took care of 10 years of a/c gunk built up on the fins!

Reviewed in the United States on April 23, 2024

Scent: LemonSize: 1.19 Pound (Pack of 1)Verified Purchase

I just cleaned my a/c unit on the outside and inside (under the fan). It worked great! It's had grass grown into it and lots of dust from the road. this spray foam got into the many little sharp fins and dissolved the gunk that had built up. DO NOT PAY someone to clean your a/c! Pop the lid off and spray this nice smelling lemony scent all over the coils/fins then just spray off after a couple minutes. Great product!

I did buy 2 bottles and ended up using them both. I will buy 2 more bottles just to keep until next time.

cleans fine, messy applicator (UPDATED)

Reviewed in the United States on June 2, 2020

Scent: LemonSize: 1.19 Pound (Pack of 1)Verified Purchase

UPDATE Jun 2021: I tried this product again this year and the applicator actually seemed to work better. Still a bit messier than I like, but since I wear gloves for this kind of work normally... The thing that prompted me to update my review is I noticed I only needed 1.5 cans for my whole-house condenser unit. With other brands I've always needed 2-3 cans. That savings brings my rating up to 5 stars.

It still cleans as well as before, the coils are visibly cleaner afterwards, and there's color to the rinse water showing dirt was removed.

If you weren't already aware, using a product like this improves the lifespan AND the efficiency of your HVAC unit, without an expensive service tech visit.

Original review follows
--
Coil cleaner, of the sort homeowners like me use to loosen and remove dirt from outside HVAC condenser units.

For that purpose, the foaming cleanser works well enough-- apply to the condenser fins, it foams up, let it sit a few minutes, then rinse it off (since this type of condenser is not "self-rinsing" like a window unit). Removing a year's dirt went smoothly.

So why the 3-star rating? The applicator is way messier and mediocre than it should be (compared to other brands I've used). The spray nozzle is tiny but takes a lot of pressure to trigger. Foam builds up on it and drips down the can. It takes a lot of pressure to keep the nozzle engaged for long enough to use up a can. The can can't be held sideways or upside down, which makes application at weird spots like "back of the unit" much harder.

Essentially, the part of the can the user interacts with is more painful to use than it should be. If you get this product, it'll work, but first try to find one with a more functional nozzle.
