Essential oils work quite well in the laundry, not just for their aromas, but for cleaning benefits as well. Add 8-15 drops essential oil per cap of unscented liquid detergent or 3-5 drops to the rinse cycle.
Lavender and citrus oils like orange do very well with laundry because of their ability to help fight grease, stains and odor. Tea Tree is a powerful disinfectant, use with pet laundry, and kitchen towels. Try Peppermint or our Energize Blend for your workout clothes (then hang to dry for maximum benefit). Also, according to a study at the University of Sydney Australia, adding Eucalyptus essential oil to your wash will eliminate 99% of dust mites from bedding.
Other than a very faint smell, the scent you use in the washer does not stick with the clothing through the drying cycle. Essential oils in the washer are mostly for their odor eliminating and bacteria fighting capabilities.
In the dryer, you can add essential oils to wool dryer balls or a washcloth to lightly scent your clothes and linens. Essential oils dissipate quickly when heated, so if you want a more powerful aroma, make the addition toward the end of the cycle. Or use the air-dry option to remove heat from the process entirely. (Do not add the oils directly to your fabrics).
