Wax melts are very easy to use. You simply take your wax melt and place one or more in diffuser provided. Then light your tea light under the diffuser. When you are finished using them, you just turn off or remove the heat source and the wax will solidify until you are ready to use it again. When you are ready to use it again, just turn the warmer back on or light the tea light (depending on which type of warmer you have). When you are ready to dispose of the used wax melts, you just allow the wax to harden, then just allow it to heat for a few minutes to loosen it and it should pop right out.
