Diaper Buddies can be used to deodorize your diaper pail, and they can be used as laundry boosters. One diaper buddy is enough for a regular pail but you may need two for a large pail. When you are ready to wash, just dump the Diaper Buddies into the machine along with the clothes and it will act as a laundry booster. Laundry detergent should still be used but other additives are not necessary. These come to you shrinkwrapped in groups of six inside a resealable bag for maximum freshness. Just add a Diaper Buddy to your clean pail before you put the dirty diapers in. The ball will act to absorb odors and add a fresh scent to your pail. When it is time to wash your diapers you throw it into the washing machine with your diapers and it works as a laundry booster for cleaner diapers.
