Brass valve parts cleaning

[Belmont]

I am rebuilding and O² cleaning a Beuchat double outlet Y-valve.
Some of the inner brass components are discolored and greasy looking but not corroded or pitted. I would like to know what to use to bring back the original brass colour. I was thinking of some fine buffing with a Dremel or soaking in CLR. Some have told me I could not make the parts O² clean. It' a pain to get parts from France. Any suggestions?

Thank you

warm Lime juice, or warm tomato juice will often clean brass and copper parts.

If O2 cleaning is what you are trying to do: dismantle the valve completely, soak, agitate, and brush all components thoroughly with a clean toothbrush in water and a liquid dishwashing detergent like Joy or Dawn. Then thoroughly rinse, rinse again just to be sure, then dry. To brighten the color of the brass, I don't know what to use that is sure to be O2 compatible.

When you reassemble it, be sure to use an O2 compatible grease like Chritolube or Tribolube71.

One other thing. Make sure your hands and tools are grease free too.
