Apple Store experiences can be so weird. I went in to buy some cleaning solution...they used to sell iKlear I think. I asked a floor employee when I could not find anything. The guy was like "you don't need any solution, all you need is a microfiber cloth". So I pointed over his shoulder and said "it looks like you are using some sort of cleaner here in the store". He again said, all I needed was microfiber. So I gave in to this young Jedi and figured I would just buy some microfiber. But they don't sell that either.
