Coil cleaner

[r404a]

Probably been gone over a few times...but here is a question. I used to swear by the blue stuff-Nu-Brite. I tried a different cleaner this summer, insted of blue, its brown. I can't remember the name, but it did a great job foaming, but didn't seem as harsh as the blue stuff, especially if it hits the skin. I think the pink stuff is a joke.
Anyone here tried a cleaner called "Grease-off" ? I think it is made by the Spray 9 people and it is great. Aireco sells it around here, when I can get them to stock it. I woder if it would be better for condenser coils than the foaming acid?

Good ole water is the best for the coil, and most times a normal coil will come clean with just water.

Of course, there's plenty of reasons to use coil cleaner too... greasy nasty bad coils. But if they are kept up, a good rinsing with water does the trick and it's not harsh at all.

The cleaner we use is pro-power (brown in color) made by Diversitech. the pro - green made by same co. pretty good on indoor coils. Both of these are non-acid base products, The brown product foams green dosen't. The pink acid base is good wead killer! lol.

You must not do restaurants. I can show you some coils that take 3-4 cleanings with strong coil cleaner to get all the crud out of them. You oughta see grease packed coils that have been running that way long enough that the condenser heat has baked the grease into a hard black goo. Nasty!

may have been foam-brite. Brown in color, also made by nu-calgon, similar to nu-brite, but foams up a lot more.

:o

I like the foam bite or nu-brite. The older nu-brite was really consentrated. It had to be mixed 10-1. I did this proper mix and used it on a liebert mini-mate unit, the condenser got so hot it blew the relife on the receiver.
I used some stuff this summer at a Petco that was brown and it was junk, but Petco Corp. called for it. I don't recall the product name thou.

Goodway makes a real good coil cleaner.

[whec720]

Try the Goodway coil cleaner. I've had better results with it over the Nu-Calgon cleaner.

Nope, thankfully I don't! lol I know there's cases where coil cleaner just can't be avoided.

Thankfully most of what we do, a dirty coil is just dirty with dirt and debris, not much if any oil or grease.

There is a coil cleaner that I use called Foam-n-Clean,it is brown,and it works very well.It will clean most of the coils that are pretty dirty.But if I can't clean it with that,I will break out the Nu-Brite.Oh yeah the Foam-n-Clean is made by ACE.I buy it around here at Ferguson HVAC,CC Dickson,and Totaline.

The same people that make Nubrute also have a brown coil cleaner that is NuBrite with a different foaming agent... I do not remember the name off the top of my head.

i agree- in most cases water is all that is needed. there are always concerns about using a chemical on the roof or around landscaping. I have found the brown foaming cleaner to be good if I must use a cleaner. Dilute it properly and rinse thoroughly.

You have to go with Reneuz , a 4 to 1 mix works on the worst coils . Seldom is a second wash required. However , Any coil close to a grease exhaust will require numerous washings no matter what brand of cleaner you use.

I used the brown stuff once too only to find that it smelled like urine. Oops I must have peed in that one and left it on the truck(heeheehee).

[mikelcs]

when using a bottle in the back of the service van, the bottle should be clearly marked "piss". that way you don't use the bottle for coil cleaner, or worse, a drink!

I use Black Max by hydro balance. It's non acid and foams plenty.

I've been using a foaming alkaline coil cleaner called Pro Blue this summer, don't know who makes it. I gave one unit a second coating, because it had so much pollen buildup, and after it sitting maybe a minute smoke started to roll off of it so much that it looked to be on fire. It also takes about 15 minutes to flush off of skin. :eek:

Mikelcs,

Thanks for the laugh. I'm glad someone can share in my humor.
