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) - 3 Pack

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

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!

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.

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.

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

Works very well, smells good also. Very citrus.

Work great on my condenser unit . Got rid of a lot of crud off my coil . Unit running much better.

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.

We have used this on outdoor and interior components of our "minisplit" system. Works very well. Excellent aerosol can that has distributed all of the product evenly. Foam is not too noxious and does a great job breaking down dust and moldy crud from the interior blower (Plastics), and metalic fins . We recently re-ordered another 3 can batch. ( 3 cans so far have washed up 6 heads and 3 exterior units). We have moved to wash with light water afterwards (Spray soak and wait 20-30 mins for foam to soak/ and melt away, then low pressure spray with warm water and the goop flushed clear ). Using a HVAC raincoat/funnel and hand pump seems good)

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.

very good product

Bad canister

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
