This is going to save you money, cut down on the amount of chemicals your skin and clothing come into contact with. Your fabrics will last longer without all the heavy commercial waxes, but you will find your towels as absorbent as if they had been hung out to dry, without the crispiness!
You will need:
1 c. Hair Conditioner (a large bottle of cheap conditioner from the dollar store is great for this)
1/4 c. White Vinegar
1/2 t. Sweet Orange Essential Oil (or essential oil of your choice)
In a large, clean fabric softener or bleach bottle, pour the conditioner, vinegar, and essential oil and shake well. Fill halfway with water, shake again, then top up the rest of the way with water. Use 1/4 c. with each load of laundry.
