Cleaning a Michelle Gyro SE

I've had my Gyro SE for a few months now and I love it. However, I
have managed to get finger marks in a couple of places (mainly on the
counter-weights under the platter). I was just wondering what people
here use to clean this and other decks.

The other problem (until I get a new stand and a clearcover - the
current one being too small to take the cover) is dust. I am using a
unicover which helps prevent dust getting on the platter but it still
gets to the armtube of the technoarm I am currently using. I dust this
regularly (and carefully) but was wondering if anyone has any further
tips for avoiding dust.

Thanks for any help on this folks.
