Wax paper will kinda work but it is more a hold over from days gone by when wax paper really had wax on it. I started using parchment paper but like the wax paper it sometimes works and sometimes doesn't. I have tried the thin plastic painters drop cloth and it works pretty well.
The wax on wax paper was removed when the micro wave started getting popular, people didn't like the wax in there food. My kingdom to locate the good old wax paper. Instead of auto wax a bar of paraffin wax and a bit of rubbing like waxing a surf board may be a better trick?
