You will need an iron and two paper towels.
Plug in the iron and turn it to a medium or high setting. Let it heat up for about 10 minutes.
Fold a paper towel in half twice in order to make it a thick, small square.
Place the folded paper towel underneath the wax-stained demin.
Fold the second paper towel the same way as the first and place it directly on top of the hardened candle wax.
Press the iron onto the paper towel and hold it for approximately 15 seconds.
Remove the iron and wait about 10 seconds. Then carefully pull the paper towels from the denim material. This should lift the candle wax with it.
Wash the jeans as you normally would.
