Features

  • HIGH-PRESSURE FOAMING SPRAY PENETRATES DEEP- Unlike wide-spray HVAC coil cleaners that foam on contact, Foam Blaster uses a higher-speed, higher-pressure, focused spray pattern that drives cleaner into the AC coil before foaming. This delayed foaming action is designed to reach buildup hidden below the surface to thoroughly clean dirty coils and deodorize drain pans.
  • POWERFUL ACTIVE EXPANDING FOAM LIQUIFIES GRIME - Other air conditioner coil cleaners foam up right away like shaving cream, making their cleaning ability more topical and superficial. Foam Blasters heavy-duty chemical formula activates after penetration, expanding through the coil to liquify dirt, grime, and buildup. It helps restore system efficiency while leaving behind a mild fresh scent.
  • FOR EVAPORATORS (NO-RINSE) AND CONDENSERS - The Foam Blaster AC coil cleaner foam is made for both your AC evaporator (no rinsing required) and AC condenser (light rinsing with water required). When cleaning evaporators, the condensate water from the ac unit in operation will rinse off the dirt, debris, and product.
  • CLEANS MORE THAN AC COILS - Designed for use on all HVAC units, refrigeration systems, automotive radiators, fan blades, metal filters, and more. Works great as a mini split cleaning kit, car AC cleaner, radiator cleaner, HVAC coil cleaner, refrigerator coil cleaner, evaporator coil cleaner, and condenser coil cleaner.

Description

Visit the Store Visit the Store How does the Foam Blaster clean? Foam Blaster expands into hard to reach locations making contact contaminants. The foam will convert to a liquid, emulsifying dirt, grease, oil, and other residues quickly and easily. What makes Foam Blaster special for use on Air Conditioning/HVAC coils? Foam Blaster is specifically formulated with unique surfactants and cleaners that have been developed into a foaming, self-rinsing chemistry that is designed specifically for the types of dirt and debris, materials, and design of HVAC equipment. How many coils, or what size coil can be cleaned with one can of Foam Blaster? Usage depends on system size and coil condition—Typically, 1 can for a 3-ton evaporator and up to 3 cans for a 3-ton condenser unit. Can Foam Blaster be used on any type of Air Conditioning/HVAC coil? Yes, Foam Blaster is specially designed to be safe for all types of evaporator and condenser coils. These coils include... tube and fin coils, microchannel coils, and coated coils. Does Foam Blaster need to be rinsed off the surface of the coil? Indoor coils (evaporators) will self-rinse from the condensation that naturally forms during use and generally do not require any additional rinsing. Outdoor coils (condensers) will need to be rinsed off with a garden hose after application.

  • Good Product
Size: 18 Fl Oz (Pack of 1)
Good results with cleaning HVAC unit, spray is easy to apply and wash out with water.

  • Works great on my U shaped window unit
Size: 18 Fl Oz (Pack of 1)
I used this on my indoor window AC (U shaped) and it worked perfectly. My ac unit didn't smell bad (no mildew or anything like that), but it didn't smell clean either, if that makes sense. This has a clean, almost citrus-y scent and foams up as soon as it hits the fins on the coils. I was worried because it doesn't come with a straw to direct the spray but it comes out in a straight stream and is easy to aim. I let it sit for the recommended amount of time and then rinsed with distilled water. If it was full on summer with humidity I wouldn't have even needed that last step because the condensation would have rinsed it off. I was expecting bad times because of the warning label but it wasnt bad at all and I just left the bathroom fan running. Definitely would recommend for window AC units if you can easily reach the inside coils. ... show more

Great stuff. Worked perfectly and easy to use. Air conditioner hadn’t been cleaned in 3 years! Looks brand new.

  • You will need the 3 pack
Size: 18 Fl Oz (Pack of 3)
Yes you will need all three cans to do an outdoor unit. Seems to work well and the rinse off didn’t kill the plants surrounding the outdoor unit. Taking all the panels off the unit to get to the coils was the real challenge. Spray came out the can easily and foamed. It did remove easily with water and had no really harsh smell. ... show more

  • Easy and works well!
Size: 18 Fl Oz (Pack of 1)
This cleaner sprays into your coils as a thin stream and then expands into a larger foam on contact. This works and cleans surprisingly well and I can definitely recommend it. Also, the scent is of gentle citrus, and is delightful. I’ve used it indoors on convector coils and am very happy with the results! ... show more

  • Cleaning the coils on a heat pump.
Size: 18 Fl Oz (Pack of 1)
worked great. My heat pump is 29 years old and I'm doing everything I can to keep it going. The fan motor was going out so while I was replacing it I cleaned the coils. A lot of stuff came out. Hopefully I can get a few more years out of it.
