Wax melts offer fragrances similar to scented candles, without a wick and potentially without a flame. Wax melts release fragrance as they get warm and begin to melt. The heat source may be a light bulb, electricity or a tealight candle, depending on the type of receptacle used to warm the wax in your wax tart warmer. Some warmers require wax melts or tarts of a specific size, so be sure to check the device before purchasing scented wax melts.

Flame-Powered Tart Warmers

Step 1

Inspect the bowl portion of the wax warmer and wipe it out with a paper towel to remove dust. Set the bowl atop the burner base, if the pieces are separate. If the bowl is cracked or has any holes in it, it is not safe, and the warmer should be replaced.

Step 2

Place a wax melt inside the bowl of the warmer. If the melts are small and the warmer's bowl is comparatively large, add another melt of the same fragrance.

Electric Tart Warmers

...

Step 5

Place a wax melt or tart in the bowl portion of a bowl-style electric warmer or slide a wax melt into the wax chamber of a tiny nightlight-style burner.The design varies based on brand, but some brands require melts specific to one style of warmer. Any warmer with a bowl on top fits a vast selection of wax melts.

Step 6

Plug the electric wax warmer into a wall outlet. Flip the switch on the warmer to turn it on; many of these feature a light bulb so it is easy to tell when the warmer is on.

Step 7

Turn the wax warmer off when you are finished using it and unplug it. If the bowl-style warmer is as small as a nightlight and rests against the outlet, allow the wax to harden before removing the device from the outlet to avoid spilling the wax. Remove hardened wax from the bowl once the wax cools by prying it out with a plastic knife, or leave it in the bowl if you wish to reuse it.
