Rectorseal Clean-N-Safe 83780 Coil Cleaner, Non- Acid Deep Cleaning Foam, Easy Application for HVAC Cleaning and Corrosion Protection, Aerosol Spray, HVAC, 20 oz.

I wish I had taken a picture of this when I used it. It worked great! I couldn't believe all the crud that came out of my AC. I did use it a few times till the can was gone. It foamed up and cleared all the gunk out. Easy to use no problems there. 100% will buy again when I need it.

Worked amazingly well!! Cut the grime out of my AC coils!! Helped knock off more than $100 from my electric bill! Would highly recommend.

Spray this into AC condenser and evaporator coils. The foam expands as it works, pushing accumulated grime out of the coils. On a window unit I highly recommend rinsing the coils with water after the foam has cleaned the coils. The condenser fan on window units slings condensate in the pan on the condenser coils, boosting efficiency. The bottom of the fan churning the coil cleaner in the condensate pan causes it to foam again, spewing foam out of the openings on the unit. It's temporary, but a bit messy before it resolves itself.

It did better than expected. Cleaned my old AC and helped it to run more efficiently.

If you want to use this in your car like I did in my Tesla model 3 you'll need to fabricate some quarter inch tubing to put on it so you can get down into the coils. I heated up the tubing pressed it on the nozzle and then held it on with a zip tie and it worked fine. Scent his mild.

Foams much better than others and has a good range. Others don't foam as much and you have to get right up to the coil when spraying. The range of the Rectorseal made my life easier working in a cramped air handler in an attic. It does have a bit of an odor and I recommend rinsing your evaporator coil after it has done it's work.

Best cleaner I've tried on my ac coils so far and I'm the type to keep my ac like new especially mini split evaporater coils they get nasty !!!

It works fine. The smell is not pleasant, though. I was not wowed by the cleaning foam. I would not purchase again because I have used others that were great.
