Frost King ACF19 Air Conditioner Coil Foaming Cleaner, 19 oz

No chemical smell, fast and effective. What more could you ask for? It's also priced right. Most importantly, however, is the pressure was enough to force the foam into the fins for deep cleaning, but not so forceful as to cause too much overspray everywhere. Three-quarters of a can did a small 8000-btu unit, so a single can should do a room-size 1000-btu unit just fine.

Our 4year old portable air conditioner had a horrible smell when on, I drained it but still had that bad smell. I actually started looking around for a dead mouse. When I determined there was no mouse, I did some research. I watched videos and read HVAC blogs, when I was satisfied the coils need cleaned, I found this product at Walmart. Came home from work poured myself a glass of wine, got my thesaurus so I had a variety of swear words at hand then took the unit to the front porch. I instantly found out I could not remove the vented casing to get to the coils as the video showed, (Glad I had that thesaurus) so I shook the can and sprayed into the vent that covered the coils and hoped for the best. I let it sit for about a half hour, then plugged it in and I'm thrilled to report the smell is gone. It has been replaced with a nice citrus fragrance. I thought I was going to have to replace the whole unit, but this can of coil cleaner saved me hundreds of dollars. I do recommend it.

Worked well. Got the debris on the outside lose by spraying on the inside. The foam expands and loosens the debris and pushes it out of the fins. Only required using the supplied brush in one spot and it also straightened some bent over fins. Will purchase again for next years A/c maintenance.

Window a/c unit was VERY dirty. This product worked VERY well. I cannot believe how clean the air conditioner was afterwards. I will DEFINITELY purchase this again. It is so easy to use it's unbelievable.

I was skeptical about this working lol but let me tell you! the nasty smell coming from my Window AC is gone! Now I did spray the foam and use the little scrub lid 3x just because of how dirty my window AC was! but the results are impressive!

I would highly recommend this product but buy two cans because one wasn't enough to do a mid sized unit. I would also recommend you look to see that whatever product you buy from Walmart.com for pick up is at the store nearest you prior to clicking the 'pay now' button! I didn't like that I had to drive so far to pick it up at a Walmart not at all close to me, but that isn't the products fault.

I received some BIG 19 oz. cans of Frost Ki g and some small 19 oz. cans. yes, both cans of different sizes say 19oz. ?? someone's lieing. zoom in to see ounces.

Well, I ordered the Frost King brand from Wal-Mart and was delivered a completely different brand in a box from Home Depot. Wal-Mart then sent me an email that my "order had been delivered". I was confused about how that happened? I used the other brand, which I needed, so the job was done. It was a truly odd transaction!

I did not get Frost King product, instead was send a generic coil cleaner, very disappointed. And it came from Home Depot not Walmart. Will not be doing this again. I would give 0 stars if I could

It was a good value for the price, but it doesn't smell good, It smells horrible, it's just a cleaner not a deodorizing and cleaner that's why this one is cheap, but I was trying to get rid of that mold smell in my mini split and it didn't do anything at all whatsoever
