...Tea Tree Oil.
I make my own additive to save money. The additive I bought cost $19.99 per 32 ounce bottle. I make 32 ounces for around $6, a whooping 70% savings! Easy, convenient and all natural. I recommend this home mixture to experience extra clean and extra fragrant clothes. Please note that the Tea Tree Oil itself has a very powerful fragrance. Your clothes will not retain the smell of the Tea Tree Oil even if you don't use fabric softener. Wash a regular load of laundry using your regular detergent, bleach and softener adding the Tea Tree Oil mixture as an additional cleansing step. The result is addicting! I never wash clothes without it!
