RectorSeal Foam-A-Coil 82632 Coil Cleaner, Superior Penetrating Surfactant- Aided Foam Lifts & Removes Grime and Grease, Indoor & Outdoor use, HVAC, 1 Gallon

Works as advertised. Make surr to get a sprayer that will foam the liquid for best results

I just opened the package. The bottle was on its side with some liquid leaking out over my other items 😔 the foaming only happened when mixing with warm water. Nothing happened with cold. Application happened at 745am and I rinsed with clean water at 845 to give a deeper clean for 2 window air units. Used first on the outside portions. After a complete rinse I was pleased with how much crud was removed. It has no harsh scent. Negative no safety seal. Will try again because not much as used so think a good value for the cost

This worked amazing. The ac's in this rental are prone to mold build up. This is the first time I tried this product. They look bran new. Easy to apply and easy to rinse off. The areas with heavy build up only needed a damp cloth to wipe off. I will buy again.

Cleans very well. Saves me a lot of scrubbing.

This stuff doesn't foam and that's part of the cleaning process but you don't have to worry about the foaming because it does nothing about cleaning might as well just used water. Should be a recourse for this but it's Amazon it's about the money. FYI Don't buy

Didn't come with a seal end up spilling in bottom of box

Works well

Didn’t foam as advertised but did clean dirt and cottonseed from spiny fin condenser coil.
