If its just surface dust, usually a lens cleaning cloth works for me - the alcohol swabs I thought would have worked as I have used them successfully before on scope stuff & previous job using telescopes). If I have something that is very difficult to remove I usually go with acetone. This is harsh though and I caution it's usage - my favoured method was a cotton bud dipped in the stuff, wipe ONLY on the glass affected and avoid getting on rubber/plastic pieces (we were always told by our microscope mechanic is degraded these parts - even though he mostly used acetone as well). If you don't have acetone nail polish remover is almost all acetone & makes a great substitute. Avoid the herbal / environmentally freindly nail polish as they don't have the acetone.
