Best cleaner for dormant R12 system?
The air conditioning system has been without the compressor and the lines left open for 8+ years. I replaced the evaporator with a used one when i had the engine out. There old evaporator was cut to clear the headers. I have two original A6 compressors from other Electras and the remaining lines.
What is the best method to clean the condenser, evaporator, compressor & lines? I've read that i should use mineral oil in the compressor to clean it until it comes out clean. Is brake clean acceptable to use to clean the lines? I'm planning on blowing compressed air through everything afterwards to prevent any dilution of the oil.
Also i haven't found O-ring kits so i was just planning on buying the assortment.
New TXV valve, accumulator/drier and i should be good to go. Got an R12 machine too.
