90-298 Coil Safe Professional Grade Neutral pH Evaporator and Condenser Coil Cleaner, 1 gal Container, Green

Good!

Since I am super sensitive to smells, I was worried about using this product on the inside air handler coils, as it does have a faint fragrance. I used 1 part cleaner to 2 parts water, rinsed it well with a garden hose, only turned on 1/3 (also had a wet vac standing by, in case the drain was overwhelmed, which it didn't), and after it fully dried, there was no smell. Update: After a couple of 100F days, I can report that the system is notably more efficient (the air is colder) after the cleaning, it had been 10 yrs since last cleaning. And there is no smell in house when it runs, if anything, it smells cleaner. I also replaced the start capacitor for the air handler fan.

This worked great with cleaning our heat pumps but it is a bit strong. It does dissipate after an hour or so. Would buy again.

Works Great. I am glad I ordered the liquid, not the foam because my mini split was so dirty after almost 7 years. I am to do few shots of this product waiting 15 min between and rinse with garden hose. The result is amazing. looks new now. I spend little less than the half because my mini split was need it. Next time, I will do it more often and will need less product. Thanks again

Good price here. Used to buy via ezybuy. Kinda troublesome. Now it's sold here. I usually do rinse with fresh water though after using this product. Dilute accordingly. Check the instructions.
