isopropyl alcohol works. TFE is better, if you have some stashed.

If you can find them anywhere, Texwipe made a plastic wand that looks like
a tongue depressor with a slit down the middle and a lint free sleeve
called the Texsleeve (tx300 sleeve, tx800 wand) that you would use to clean heads

Minor head crashes leave a tar-like residue that you need to remove. A pack inspector
is a handy thing to have (spinle with microscope and illuminator on the rack and pinion)
to look for surface damage.
