Rinse your leftover wax cappings. When you spin honey there is always leftover wax and there's always a bit of honey left in that wax. Put all cappings in a large bowl and fill with water. Let the wax soak for at least one hour. Drain and repeat. You will want to rinse at least three times. 

Strain off as much water as possible. I use an old sieve and allow my wax to just sit in it for awhile so most of the water drains off.

Place wax on a screen lined with a paper towel. The paper towel will help catch any impurities in the wax.

Place screen on top of a baking dish filled with ¼" of water.

Place baking dish on an old baking sheet.

Place in a 250 degree oven.

When wax has melted, add additional wax if available.

When all wax has melted, turn off oven and allow to fully cool.

When oven and wax are fully cooled, the wax will  harden and turn yellow. Remove from oven.

Discard paper towel and water in baking dish.

Remove wax from baking dish.
