How can I solve the keyboard touching screen issue

I'm using the foam that came with my MBP when I close the lid. It protects it while the laptop is closed and keeps the dusts off the keyboards and speakers while in the clamshell mode.

 

microfiber cloths for glasses?

Pretty much any cloth will do.. you don't need anything super fancy unless you want it lol. A temporary solution can be a cut up shirt or just paper towel for now till you get one you like or somethhing. Maybe not paper towel but yeah..

If the above solutions don't work for you, do a search in Google. There are a lot of these protectors on the market that they're easy to find. They're also very expensive for what they are, so I'd rather find any other alternative.

 

+1 on the Radtech product. I've been using it since the second week of owning my MBP. I'm very pleased.
