Yes of course! We have the perfect solution for this, our exquisite parfum oil diffuser refill. The easiest way to clean out the remaining wax is to use a spoon or kitchen towel and scoop out the wax. You can then polish it with vinegar or warm soapy water (be careful of the label). The empty vessel can be used as a cold drink drinking glass, vase, or for things in your bathroom like cotton buds and cotton wool, hair pins and hair ties. Use it for whatever you wish. We recommend not placing hot drinks in the glass.
