Removes dirt and mold

Francis J. Fisherβ€”December 28, 2025βœ“ Verified purchase

I clean my inside coils twice a year. Spring and fall. This stuff works great. Keeps the unit efficient, and keeps the air smelling clean and fresh. Easy to use. Just remove your air filter, and front panel, spray and forget. It foams extremely well. Removed dirt and even mold. Read more

Who You Gonna Call? Gunk Busters!

Critical Buyerβ€”August 28, 2025βœ“ Verified purchase

Had a ridiculous amount of buildup on the evaporator coils in my internal AC unit. The buildup was that greasy, black sticky gunk reinforced with fine dog hair that had escaped my plenum air filters. Bought one can of this foaming cleaner per side of the A-frame and applied liberally, first on the top-side (which was clean, but the hope was to have it flow through and loosen the gunk from the bottom), let it sit for about fifteen minutes. Then went back and sprayed the underside of the coils, using about half the can per side. Let sit for about fifteen minutes and came back to a noticeably cleaner set of coils. Repeated this process and saw a huge difference. I would call this foamer very effective, easy to use, and a good value for the price. Do note: You will want to use eye protection and wear sleeves when you apply this foam. It does burn a bit when it hits your skin, it is irritating if you breathe it in (so a respirator or good quality mask isn't a bad idea), and you'll want to consider gloves. You DO NOT want to get this in your eyes. Also, make sure you have a gallon or so of vinegar on standby. The gunk that melts/falls off will get collected and condensate water will flush it down your drain line. You won't want it to clog your line, so flushing it with vinegar during and shortly after the process is a good idea. Read more

Frustrating to apply.

Steveβ€”November 17, 2025βœ“ Verified purchase

The product didn't dispense very well. Doesn't seem like the right nozzle for the job. It would also be better if the can dispensed at any angle. I believe the cleaning agent worked but it was not easy to get it where you wanted it . Read more
