About the rubbing alcohol, DO NOT USE TOO MUCH! I only used a very very very tiny amount just dabbed on a paper towel.
Car wax? on a laptop? What are you thinking? Do you want to ruin your computer? I don't see how that could in any way be beneficial to a computer. I can only see it screwing it up, wax getting into spaces between the chassis and such, short circuiting stuff, clogging up keys on the keyboard. That seems like it could really be a serious mess.
