LIQUID LAUNDRY SOAP

In a large bucket, mix together ½ cup washing soda, ½ cup borax, ½ cup liquid castile soap, 2-3 teaspoons lavender or lemongrass essential oil and 7 litres hot water. Mix until the soda, borax and soap dissolves. Store in glass bottles or recycled, clean plastic laundry containers. Use ¼ cup per load, shaking before use.
