Over time, you can see how the keys begin to be coated with the oil from your fingers and you can especially see it on the spacebar, where one spot of the spacebar is shiny from the oil from your fingers and the rest is just, normal.
Despite the obvious, how should I take into consideration to cleaning the oil off the keys? Is there anything special I should be using and is there a different cleaning method towards keys on my laptop or keys on the desktop's keyboard?
