[Pepperpixie]

As you can see from piccy my coffee table is looking very tired and unloved, but i'm not very good with diy etc how can i revive this, there are pen marks, greasy finger prints and milk stains on it. Can i sand it down by hand with a very fine sand paper??? Also, i don't really like varnish so what's best to use on it afterwards, a wax or an oil???
