Leak Saver Foam Blaster AC Coil Cleaner Foam Spray | HVAC Coil Cleaner for AC Unit | Professional Deep-Penetrating Formula for Evaporator (No Rinse) & Condenser (Light Rinse)

Good results with cleaning HVAC unit, spray is easy to apply and wash out with water.

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.

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

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.

Works great. We had to use all 3 cans on our 3 ton unit, probably could have used a 4th but 3 did a good job. Sprayed on and you can literally see the dirt coming out immediately. Let it sit til it wasn't as foamy and rinsed clean with water hose. I will continue to purchase and use at least once a year.

Works great. Smells good. Easy to apply. And makes my AC run much cooler and better. Definitely will be buying again

Watched a few videos before making this purchase. The day of cleaning, I removed the top of the ac unit along with the side covers. Lightly vacuumed the coils and bottom and then sprayed the inner and outer coils with the cleaner. It didn't seem to spray out and foam as much as what I watched in the videos but it did appear to work at getting the grime to the surface. Afterwards (15 min), I hosed off the coils several times and they looked pretty clean. Overall I'm satisfied with this product, the citrus scent was not overwhelming and I went through 3 full cans to do my 3 1/2 ton condenser.

This stuff works great! We get a ton of cotton from those evil cottonwood trees every summer and this worked very well for that!

This stuff works great!...having a retired uncle in the HVAC, he tought me to make sure the condensor & coils were always in tip top shape, in doing so keep them clean. Although he didnt use this stuff, he was on the commercial side - i tried it and can tell it works great.

Worked well followed the instructions for once and it did what it said it was going to do dissolve the dirt and then I just sprayed it off.

used 2 cans to spray on my outdoor ac unit, foam works its way into the fins really well before I did the final rinse with a garden hose on light spray

Bad canister

Good value
