Improve AC Performance for $6

Revival, can these be used on the tranny cooler as well?

 

I would do it. I think it would be ok to use on anything with fins.

 

I've got gallons of Nu-Brite - with your experience - any suggestion - you used the purple compressor cleaner not the green condenser cleaner - correct ? the front bumper is plastic so any worries vs the metal fenders as far as "it will strip paint if you aren’t careful" ?? Any reply appreciated.

 

I used the purple “condenser coil cleaner” Part number 4291-08. I think the clear coated paint it will be ok, just don’t use it in direct sun light or allow it to dry. On my home AC condenser it stripped the black paint off the fins. (It’s my understanding that they make a version that is less harsh than the one I used). But yeah I would just be very careful, you will certainly want to rinse this stuff off sooner than later. I think you’ll be ok with the front bumper just don’t intentionally spray a bunch on it, if you get some on just rinse it off. Maybe keep a bucket of car soap near by so you can wipe down any painted areas after to remove any residue of the nu brite.
