In a small bowl or jar, mix the white vinegar and water.
Add the essential oils and stir well to combine.
Cut the fabric into squares, or use old washcloths or t-shirts (about 6–8 pieces).
Place the fabric squares into an airtight container.
Pour the vinegar mixture over the fabric squares and let them soak for at least 1 hour. You can leave them overnight if you prefer.
Once soaked, wring out any excess liquid from the fabric squares.
To Use:
Toss 1–2 of the fabric sheets into the dryer with your laundry load.
After use, store the fabric sheets back in the container and reuse them for several loads (typically 5–10 times) before re-soaking.
