There is copper/copper and copper/brass joints to make.

copper to brass can use silphos. just don't get brass hot. if it is pink it is going to melt. Needs flux too. idk if it is helpful but pink flux is shit. white flux works effectively.

I was thinking of a wire wheel and sand paper before some kind of acid flux etc? Am I on the right track?

Cheers

If you are using silphos, just get it 'Bright' with sand-paper, wipe with clean-cloth, dont touch it with fingers
