Wax Machine

My wife owns a machine in paraffin for a few years now. He has accumulated a little dirt and dead skin on the bottom of the machine. Is there a trick to clean the old wax before putting waxinto new machine?

Just turn the machine on low and only one minute just to Lossen a bit, then the big block of dirty wax should just slide right on, after you can just wipe the interior with hot water, and any wax thats stuck around it peels right side of good with a little heat and a butter knife (or spatula), then just add the new wax, connect and enjoy
