Fresh Peppermint

Most wax melts will warm in an electric warmer with a strong scent throw for approximately 8 hours. Add 2 cubes to your wax warmer to start. That should last you for several hours. It's best to turn off the wax warmer after 4 hours. 

When you warm your wax melt continuously for more than 6 hours the scent fades quicker. Personally, I find that 4 hours is a sufficient amount of time to fragrance a room and allow the fragrance to linger. Each scent is different but you should expect at least 8-10 hours from two cubes.
