I use 1000 grit paper or those plastic felt pads for cleaning copper
tubing before soldering. If you get the pads watch out not to buy the very
course variety they make ugly deep scratches. The pads are reuseable, from
the paper i just rip off a piece maybe an inch square, it clogs up fast
with the copper so not really good for more than one board.
Steel wool can embed small iron particles in the copper, if this is a
problem i'll let you be the judge of.
After the sanding (just enough to get sanding marks on the whole surface)
i wipe with alcohol.
This is a dry / no water process, which is why i like it. It makes little
mess, only the minimal copper sanding dust.
