Refrigerator contamination.

I have a refrigerator. Ive installed 2 compressors. Ive change out the dryers. Ive pump the frig down into vacume. Made sure the vacume holds. then supplied the r134. Im suspicious about contamination inside the copper lines.Is there a sure fire way to clean this internal system for future reference?

I'm suspicious about...
I'm suspicious about the initial quality/design of the appliance maker
and the refr mechanic who keeps flogging this thing.

Refrigerator contamination.

one of the surest ways to remove acid is keep changing the loi as it will travel thru the system and wash the acid back to the oil sump....sounds easy but commercially it's the way it is done with all the right fittings and isolating valves in the on the compressor....changing of the dryer will catch it but the labor is a killer.if you installed isolating vlaves on both sides and flare one in with a shradder mounted dryer ..then you could flip one in with no torching....once a system is burnt it is never going to be as if it never happened no matter what you do...seen techs mickey mouse the acid clean up and the compressor crappped by weeks end and i'm talking a $20,000 60ton compressors.... crane and all...

Probably should have soldered a schraeder valve on the high side to get a complete picture of what's happening in there. Two gauge's are better than one, especially with the problems your'e having.
