Quick screen wipe

The iBook screen has a lot of dust and other particles. Easily visible.

What can I use to wipe it off and give a fresh look?
I don't want to buy those laptop screen wiper products. Looking for other methods that is SAFE. Thanks.

i have this cloth that my dad gave to me, it sucks up dust really well with a couple of wipes, cant be sure what the exact material is but it looks similar to a towel.
