For those of you that have a white macbook and have had it for any length of time will notice the discoloration of the palm rests. What once was a bright clean white macbook as turned to a rather ugly looking colour. This can be an issue when you are showing off your amazing Macbook to your PC using friends. If you are like me you tried to use a variety of cleaners, windex, etc to clean it, all of which did nothing to solve the problem. One of the best solutions is to go pick up a MR.CLEAN Magic Eraser. You will want to turn off the computer when you do this. Then apply the Damp Magic Eraser to the affected areas and wipe clean with a second cloth so as to remove the chemicals and to dry it off. This should do the trick. Check out this before and after shot.
I simpler, non toxic solution is a rubber eraser. Works wonder. It does the same job without the mess.
