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.

  • 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.

  • 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

  • Smells good.
Size: 18 Fl Oz (Pack of 1)
This foam blaster is a game-changer for keeping my AC unit in top shape! It makes cleaning the coils so much easier and faster than I expected. The foam expands nicely and gets into all the nooks and crannies. My system is definitely running more efficiently after using this product. I highly recommend it for anyone looking for a simple yet effective way to maintain their air conditioning. ... show more

  • Worked fine I just didn't leave on too long
Size: 18 Fl Oz (Pack of 6)
And I maybe should have tried using an ultra soft brush (almost like a newborn hair brush level soft, maybe one firmness up) but I was too scared of bending fins. With 2.5 hours of rinsing afterwards it got my outdoor unit - which had black soot 'caught' fungus from the nearby gardenia bushes - 90% cleaner. ... show more

  • Great stuff !!!

  • 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

  • WOW!!
Size: 18 Fl Oz (Pack of 1)
Used this for cleaning my two window AC units before it gets hot out...this stuff really works great. Wish I had taken a few photos - but, once I sprayed this onto the coils - it just disintegrated the dirt and dust. I soaked the coils and let sit for about 10 minutes. Then everything wiped clean. I would suggest having a garbage bag or tarp underneath since this does pull all of the dirt downwards. Everything is super clean!! ... show more
