First off, if you are using a good quality candle, there should not

be any left over wax. Good quality candles burn away completely

except for the metal wick holder. If you do have left over wax, the

easiest and quickest way to get it out is pop it in the freezer for

about 5 minutes then hold the container in one hand and use a finger

or two from the other to pull the wax out. The warmth from your hand

will heat the glass container quicker than the wax causing them to

seperate. Please do not use a knife as you could injure your self and

or break the glass container.
