    Is there a way to clean tarnish from old copper fittings? I have quite a few copper fittings that are fairly tarnished, and although I can clean them one by one at the time of use, is there a way to clean the batch? Tarn-X or Brasso or similar which won't contaminate the system.

    Be careful with that TSP. That's some raunchy stuff.

    I see someone has a little time on their hands...

    Why not clean them as you use them? Even with dipping, rinsing and drying them, won't they just tarnish again if not use right away? I always had tarnish on my fittings when I went to use them, all I ever do is just brush them out real good and sandcloth the fitting ends. Never had a problem yet.

    i was always taugt to be prepared for possibly using an extra fitting or two. it happens, and its cheaper to buy extra than to go back to the supply house. when you fininsh the job, any extra fittings go into a five gallen bucket. they may only be used again under two circumstances. 1- an emergency situation such as a late night or weekend repair that MUST be made, or 2- first week of december to be redeemed as part of the christmas bonus.

    A buddy of mine in this business has told me about using citric acid to clean copper fittings.
    I got a big bottle of RealLemon and a handful of tarnished copper fittings and put both of them into a small bucket. I stirred them around a few times, rinsed them off well with water and dried them. They weren't "shiny" clean but, they were clean and worked quite well. Minimal polishing with sandcloth and so far, no corroded solder joints.
    There is a product sold in supply houses made for cleaning copper. You wipe the stuff onto the copper, wipe it off and the copper is shiny clean. Can't remember the name of it but, it is mostly citric acid.

    That's exactly how it happens, extra fittings from long finished jobs in a plastic crate. they start a 3/8" and go to 1-5/8".
