Nu-Calgon 4171-75 Evap Foam No Rinse Evaporator Coil Cleaner, 18 oz. (Pack of 2)

I use it on my Mitsubishi split system evaporator at the beginning of every summer. Pleased with the results

Restored my A/C evaporator coils to like new, clean condition. The efficiency and air flow through the coils is much improved. I love it.

Can big enough to clean both RV Air conditioners. Worked good and did not require rinsing.

The product worked as advertised for the type coils I was cleaning foamed up nicely (shake for sure before spraying) the only thing that worried me was the proprietary ingredients being toxic to animals. Basically anti freeze. Not certain what a good solution to that issue would be. I picked a very untravelled spot in my yard to rinse and used plenty of water to clean and to let the cleaner soak into the ground, til it dries. My dog is fine. Be cautious and aware of hazard to animals. Yours or other wild critters possibly entering and exiting your yard. Same caution if pets if you have a professional clean your coils. It is a good product and works as intended. As for odors while using. Not a bad idea to wear a respirator. But open air well ventilated area, is probably okay.

Easy to use good price.

Works great, loosened and cleaned all the accumulation between the fins of the mini-split inside unit. Made a big difference in the smell and feel of the air pushed out of the unit. I placed gel sticks on the water tray to keep from developing smells from there.

It does what it is supposed to do.

Cleaned the condenser really well. I recommend this product
