Compressed air is not adequate for anything which puts a film on the

Careful about the dry one - that can scratch. If it's pure alcohol,
there will be no residue after a couple of applications.

I've never observed a problem with this, but I would recommend good quality
swabs, fluff the end a bit, and as always BE GENTLE.
