Best way to clear gateway laptop screen and keyboard with iKlear?

I got iKlear mainly for my iPhone but I noticed that my gateway laptop screen and Gateway Laptop Keyboard are a little dirty but I did not know the proper way to clean it with iKlear. I have two microfiber cloths and a big blue one. (Best answer will go to the person who explains step by step and tell what kind of cloth to use for each step.

By the way, I want to buy the Toshiba Laptop Keyboard or Compaq Laptop Keyboard, any good suggestion on where I can get one?
