Wax tart warmers have come a long way since the very first varieties were designed decades ago. Older electric options were generally made of metal. They were difficult to clean and they used ordinary nightlight bulbs. Others were designed to use with tea light candles, and they are not nearly as safe or as stylish as the latest and greatest models that use energy-efficient LED bulbs. One thing has never changed. The tarts can be very expensive, especially name brand varieties that smell exceptionally fragrant. You do not have to use them to fill your home with amazing fragrance. Other options can be used in a wax tart warmer, and they often work just as well.
Some wax tart warmers have warranties that will become void if unapproved products are used. Also, when using anything other than wax tarts, never leave the warmer completely unattended. Do not use essential oils without combining them with beeswax or other candle wax alternatives or water. In any case, proceed with caution. Exercise commonsense, and keep the warmer and connecting cord out of reach of children and pets. It is up to you to decide if something is safe to use and/or continue using in your home or office.
Use Leftover Fragrant Candle Wax
Fragrant candle wax with a wick that has burned most of the way down can still be used. Place the container in the freezer for several minutes. Tap it lightly or pry it away from a corner and the wax should come out in one piece. If not, carefully cut it into chunks with the tip of a butter knife. Remove the scented pieces of wax, and use them in your tart warmer. If necessary, add a couple of drops of essential oil to enhance or refresh the scent.
If you have lots of leftover scented candle wax, melt it one scent at a time in a mini slow cooker. Make your own wax tarts in flexible ice cube trays that have been very lightly coated with cooking spray. For something decorative, use shaped trays. The wax tarts will pop right out, and they can be individually wrapped in cellophane and saved for future use. You can also reuse the plastic molds that once held your store-bought tarts.
Warm Vanilla Extract or Essential Oil in Water
Water and oil do not mix, but they are an ideal combination for a wax tart warmer. The water will keep the oil or extract from burning, and it will lighten the fragrance for those who prefer softer scents. Begin by adding enough water to partially fill the wax basin. Keep in mind that electricity and water do not mix either. It can be a deadly combination, and you must exercise extreme caution since the warmers are not made to hold water. Add a few drops of essential oil in a scent of your choice, or add several drops of real vanilla extract. The oil or extract will warm up along with the water, and it will emit a lovely fragrance throughout your home.
