Yes! If you love that freshly washed scent that comes with many dryer sheets or fabric conditioners, there is a way you can achieve this with your Wool Dryer Balls, and without any synthetic or toxic fragrances. Simply add a few drops of your chosen essential oils directly onto the dryer ball, or alternatively, dilute your essential oils in some lukewarm water and then saturate the entire ball in the water. You will need to then allow the dryer ball to dry out thoroughly before using it again. This is to prevent any oil marks on your laundry and to ensure the scent is released slowly throughout the cycle, leaving your laundry smelling and feeling fresh and clean. It is important to be aware that adding too much essential oil to your dryer balls could result in a dryer fire since some essential oils do pose a fire risk. For this reason, we recommend having separate sets of scented and non-scented dryer balls. Use your non-scented balls in your regular dry cycle and then swap them out for the scented dryer balls once the laundry is thoroughly dry. Only use the essential-oil infused balls on the air dry or cool dry setting, so there is no heat and no risk of fire.
