As little cutoff, wire, and grinding wheel as possible; 22g cuts with scissors, and the last 1/4" can be folded slightly in for champfer. Drill shavings can be cleaned up with a magnet, dust with a small dust pan. Not a big fan of the shop vac after the first month, unless it is the inside frame rail, or to clear debris from drain holes - that is valuable well beyond measure. The rest is like doing dishes, except, no detergent (maybe baking soda) and they get to dry in the sun.
