My aluminium mac is dirty. Time to clean it. The screen is easy – I have the cloth from the box. I just rub it with that – the screen attracts fluff (thats usually 1 pixel in size). There are no fingerprints.

I have a screen wiper thing that I got with a pack of iphone screen protector things. I googled first to see if there was anything decent that I could use, instead of just a wet sock.
