Nu-Calgon 4291-08 Nu-Brite, 1- Gallon

Oh wow just saying wow perfect work easy to clean

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!!

Works great, cleans coils good

Excellent product, but do not use this on mini splits, nor other micro channel condensers or evaporators as it will eat them alive. This should only be used by professionals, and on all non micro channel coils for best results. If you leave it on too long, you will cause damage and have been warned. If you are sure you need this, it will clean every bit of sap and dirt out of your condenser coils. I clean mine approximately every five years with a chemical similar to this for micro channel and my carrier system still looks like new eight years later.

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.

Cleans the coils. Don't breathe the mist. Wear gloves and safety glasses.

Bought this along with the hvac guys coil cleaner gun. Saw it in the back of the ac guys truck. Worked great. The units look like new and I have enough left for two more cleanings. Super cost effective. Very happy!

Works great.
