Laundry detergent has always seemed like a magical substance to me. Throw a little in the washing machine with your dirtiest clothes, and at the end of the cycle they come out clean. Now OxiClean has followed up with its own version of magic detergent. They've got a detergent ball that is left in your washing machine during and between up to 25 loads. No more detergent spills. No more bulky bottles of laundry soap. One OxiClean Detergent Ball will clean 25 loads of laundry without any measuring, pouring, or spilling. Now that sounds magic to me.
