How can one smooth the surface of a wax model for casting?

I model small sculptures for lost-wax casting in bronze, using soldering irons, dental tools, etc. These can leave small surface "trickles" or blemishes where I want smooth surfaces to represent skin.
There are actually two was to smooth the surface of waz before making either ceramic or sand cast molds. Either use a hand propane tore and just quickly skim the surface until the wax becomes even on the surface (ONLY DO SMALL AREAS AT A TIME SO THE WHOLE PIECE DOESN"T GET OVERHEATED AND TOTALLY FLOPS) also you could use paint thiner and a chamois cloth if it is a very fine fix to the wax. And once its smooth spray with alcohol so it stops the reaction of the paint thinner

Lightly rub with cheeze cloth turning the cloth as it becomes full of wax. It kind of acts like a gentle sandpaper. I made candles and it worked well.
