2 tbls natural dish soap
1 cup baking soda(takes out oil the most, is important to use)
10 drops of essential oils...lavendar, lemon.
This is for a medium load. Always wash sheets in hot water to cut the oil. You can also add a cup of Borax for whitening, and/or a cup of vinegar to take out strong smells. I don't use a dryer, I made an indoor clothesline, use dry racks, which helps add moisture to your space, as heating systems in the winter take it away. In the summer, I hang them outside on a sunny day ,makes them extra fresh, is also a natural purifier. Good luck, hope this changes your life, makes clients happy, it has mine!
