Start your own wax cycle. This way your wax gets cleaner, little by little, if you don´t treat.
In Finland my "beeswax factory", Lahtisen vahavalimo http://www.lahtisenvahavalimo.fi/, can make separately your own wax (cleaned and as foundations) if you have a lot of minimum 150kg. If you don´t have the quantity needed, then you can use solar wax melters and make foundations yourself. Solarwax melter you can even do yourself, too. Just some windowclass and plywood.
