Home made (cheap) laundry soap. Read the comments, very helpful. Optional: use Downy UNSTOPABLES™ In Wash Scent Booster for smell or lavender oil. Can use blender\food processor instead of grinding the soap, make sure to add the dry ingridients at the same time. Tip: Use the blue Dawn dish soap as a pre-treatment. *Will need to check out the DIY for the fabric softner (ingredient: Vinegar).
