Seconded
Do as standard Convert (no tricky stuff done), then cleanup using the Editor.
Every document seems to do it differently (and some even do this by section).
Find a problem: Fix it!

Pay attention to the order you choose: Fixing the hardest (complicated) first is usually best, because they may have contained a simpler issue, that is now removed, making the detection step even harder)
Repeat until you find no more things to do.
