Nu-Calgon4291-08 Nu-Brite, 1- Gallon

This stuff works great. This is what the pros use. I just put it in a garden sprayer diluted 4 to 1, no need to buy the fancy hose gun for $100 or more. Highly recommend! Have plenty left to do it again next season, probably next 2 seasons.

It is a good coil cleaner

Product works very well A little goes a long way

The product works pretty well. I’ve had some in the past that didn’t foam up well. This yields a pretty exothermic reaction. There was a tree frog in the bottom that I couldn’t reach to get out. He was dead in about 30 seconds after spraying. If you take the top off the unit, don’t put your face over the unit. The fumes are pretty tough. Also, don’t let it sit on your base too long, or it will bleach out the plastic. Otherwise, it works as expected. The pictures below are two units. They were both the same black color. I learned from the first one what can happen if it sits too long.

Muy bueno para la limpieza de coilsy y como desengrasante.

Works really well

This stuff is GREAT I cleaned my 2015 ram 2500 radiator a d all coils in front. This stuff foams and pulls crud out like crazy. As you should know wear eye protection and chemical gloves it don't burn skin but it will burn cuts and scratches on your hand. And cleaned my hvac unit coils works great. It do take alot I just used a spray bottle no scrubbing I use pressure washer. Highly recommend!!

always cleans my coils and condensers perfectly , they look new after cleaning
