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

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!!

Outside use only, can discolor painted surfaces, read warnings/common sense, MUST be diluted and totally rinsed. Best (just my opinion) to do a couple milder mixture wash and rinse instead of full strength. A pump garden sprayer with solution mix spray on, let set 15 minutes rinse off. ...side note. sprinkler systems which have well water or harsh city water dousing the AC unit, salt air, lawn mowers blowing dirt and clippings, accumulation of tree droppings etc. can destroy an AC unit...stupid is stupid does.

Dissolved all the oil and dirt, had to do it 3 times on a commercial unit but the condenser is spotless and clean again. Make sure you wear gloves! Cheaper on Zoro!!

Very solid cleaner and decent price as well.

Foamed up dirt comes out right away good product

This is the best coil cleaner I have ever used in 35 years of servicing A\C condensers. Recommend to all of my friends.

Very good product

This works just like it says have enough for two more years
