I'll second microfiber towels. I buy mine in a 24pack at costco for 10 bucks. They are great for dusting all my gear, cleaning plasma screens etc.
Dont use any sort of cleaners or polishes on the finish. If you need to, a damp cloth with plain water. I have found that with the HG finish more than dusting is needed to keep the gloss finish because they get covered in some kind of residue or dirt that clouds the finish a little which plain dusting doesnt clean off. Thats where the microfibers come in
