I just use the cloths that are used to clean phone screens, eye glasses, etc. I don't know what they're called. I don't use any kind of cleaning solution, just the cloth.
I generally use the same lens wipes I use for my glasses.

Just lens cleaners, the moistened type, or the dry ones that come with glasses. Cheers, RickO
I just wipe them down with a clean cotton t-shirt. Never use acetone. It'll melt the plastic and ruin the slab.
Worry is the interest you pay on a debt you may not owe.
Microfiber cloths I’ve heard work well too. I don’t use any solution.
91% alcohol works wonders on sticker glue, grease, sneezes, etc.
Microfiber cloth.
After you do the above, pick up a pack of these.
