Alcohol is routinely used by auto detailers to remove waxy residues. As far as my experience with the plastic part, it was left smooth and shiny, like new. The thing is - whenever you polish or even clean the finish, it is very important to use the proper tools and technique. I recommend microfiber towels only and work in straight lines - gently.
I used the Everclear, which is 190 proof grain alcohol, full strength.
