Clearing out Moisture from Instrumentation Lines

Working on my glider last night, and noticed that my static lines seem
to be more hazy than the others. It looks like there is a very fine
film of moisture on the tubing. I'm going to be putting in moisture/
filter traps on the lines, but before I do that, is there a
recommended way of drying them out a bit first?

Was thinking of blowing some low pressure air through them for a few
minutes first. Obviously, they'll be disconnected from the
instruments. Has anyone else dealt with this? And what did you do?

Thanks!
