1 quart of laundry detergent in a quart mason jar. This laundry soap is made from just 4 ingredients and is the best alternative to store-bought laundry soap. Made from baking soda, washing soda, epsom salt and sea salt. Unscented, but lavender essential oil is added as a variation for $1.00 more. Check out my homemade laundry softener listing and get the pair!
