Method of use To get the most out of your Kerzon candle, while in use it is recommended to observe certain practices. For equal distribution of the wax and efficient fragrance diffusion, let your candle burn until its entire top surface is liquid wax. To preserve its delicate scent, do not burn your candle for more than 2 to 3 hours in a row. When you blow it out, dip the wick in the wax and remove it right away making sure it is centered and straight. Regularly trim the wick to about 3 millimeters in length.
