Getting rid of that waxy build-up

When most people think they have a wax build up, most likely the culprit is a softened finish. Oil from your skin, food oils, and some detergents can break down a finish making it sticky, which in turn collects dirt and grime. If the problem lies on an area that is frequently touched. To clean it, try  using mineral spirits or naphtha as your cleaning agent.  Using a soft rag or #0000 steel wool, this is good for getting rid of a waxy build up. A word of caution though, if your finish has softened all the way through to the wood, this process could leave you with bare wood. If your finish has gotten that bad to start with, there isn't anything else you can do to reverse it other than stripping and refinishing anyway.
