I've got some beautiful cappings wax that I have a buyer for. The problem is that there are still a few dark spots where something didn't settle to the bottom. (I use a solar wax melter) I've run it thru a few time and have most of it out but want it as close to perfect as I can get it. Is there a way to filter it out? (ie. coffee filter? or would it just clog up with wax?)
