I remove liquid, warm up glass in a pot of water with some tin foil on the bottom to prevent direct contact. After it melts remove wax. Try to clean the glass thoroughly and let it dry before refilling. A funnel or plastic tube helps reduce splashing. After wax cools it will be solid on the bottom then add liquid. Main thing is to think everything through and have everything you'll need before you start (plastic containers for disposing of liquids etc) pyrex glassware is always handy but watch those vintage fluids. They're noxious and toxic.
