Does it need special wax?

It takes standard fragrance wax melts, including full-size cubes and tart cups. Break off one or two pieces and drop them in the top dish.

How does it heat the wax?

A 25 W light bulb sits under the dish and melts the wax from below. There is no flame and no soot, and the glow shows through the glass.

Not on the unit itself. Scent strength depends on how much wax you add and the size of the room; use less wax in small spaces.

A 25 W bulb, and one is included. Replace it with the same wattage; a higher-watt bulb can overheat the warmer.

Let the wax cool and harden, then press the edge to pop it out. Wipe the dish with a dry cloth rather than washing the glass body.

It is flame-free, but the glass gets warm. Unplug it when you leave the room or go to bed, and keep it off reach of children and pets.
