- 4L of distilled or filtered water
- 1 cup Velvet soap, grated
- ½ cup washing soda
- ½ cup salt
- Essential oils (optional)
Combine 1L water, soap, washing soda and salt in a saucepan. Stir over medium heat until the soap is completely dissolved. Let the mixture cool a little and add any essential oils for fragrance (optional). Pour mixture into a bucket, then fill with distilled or filtered water. Stir to combine. When cool, store in a sealed container (we reused empty 2L vinegar bottles). Shake bottles before use and use approx ¼ cup per load.
