    Cleaning refrigerant hoses/manifold

    I hooked my gauges up to a system with dye in it about a month ago and even after running about 20 pounds of refrigerant through in that time, dye just continues to leak out of the seals and gets everywhere. I hate that crap.


    What do y'all use to clean out your hoses? Is it safe to use brake cleaner because I have plenty of it.

    What gauges do you have? Digital or analog? I use 90% alchohol , but it wont get all the dye out. Dye is the devil

    I don't think brake fluid is good for the seals. But I suppose it would work if you are going to replace the seals.

    You could try some UV dye cleaner. Something like this should work.
