Place your laundry in the dryer and toss the dryer balls in. If you wish to add scent to the dryer balls, spray with the 1924 Room & Linen spray of your choice.
If your dryer balls don't see to be reducing static there are a few tips to help. First, possibly reduce your drying time, often times static occurs from clothes being over dried. If that doesn't resolve the issue, soak your dryer balls in water to "recharge" them and continue to use as stated.
When your dryer balls start to lose shape, it is time to replace them.
