Simply add a melt to your oil/wax burner – DO NOT ADD WATER. Light an unscented tealight and wait for the wax to melt, filling your room with fragrance.
Do not burn for more than four hours; do not move once wax is molten. Allow wax to solidify before moving and/or changing the melt.
Once solid, the wax disk can be eased out of the top of the burner and simply replaced.
