Part One of Two
Option #1 - The Freezer Method
Cold causes wax to harden and shrink, making it easier to remove.
Start by using a butter knife - or a spoon - to break up any large chunks of wax that remain in the container if the jar has a narrow mouth. Place the candle in the freezer for several hours, however overnight is best. Once frozen, the wax should pop out. If it is still a little stubborn, you can loosen it with a butter knife. Scrape of any leftover residue and then clean out the container with soap and water.
Option #2 - Boiling Water Method
Hot water is another great way to remove wax.
Place the candle on flat surface protected by a towel or newspaper. Use a butter knife or spoon to remove excess wax. Pour boiling water into the container, be sure to leave room at the top. The boiling water will melt the wax causing it to float to the top. Let the water cool and remove the wax. Strain the water to get rid of any small bits of wax. Scrape of any leftover residue and then clean out the container with soap and water.
Reminder - Never put wax down your sink drain
