while it would indeed be fine to just clean it with a wire brush, it DAMAGES the components when you do this.
like I said, for the Glow plug fuse, a wire brush would be ok, but not the best.
metal polish will reverse oxidation, and rinse clean with contact cleaner.
it's best to do this on parts you don't want to replace when they wear down to nothing. cleaning fuse contacts with abrasive like pencil erasers, or wire brushes will damage the fuse holder surface. it will WORK, but it's not correct, or the best practice.
for battery terminals, and cable ends, a wire brush is fine! they are parts you replace often.
fuse holders are NOT. wearing down the surfaces will alter the fuse characteristics, and eventually lead to the need for replacement.
I've been told that the MB push in fuse holders are steel... if they're not, what are they? bronze? either way, they are plated, and abrasion alters the surface and leads to failure.
