For the dryer, I got some blue balls with spikes on them, (or that's what they look like). I got them at Bed Bath & Beyond or some where like that, and then found them at Walmart. My Walmart has them for about $5.00 right now. I have 2 sets of 2 in my dryer, and they work well to keep the static away.
Make sure the balls are soft, and not hard as a rock!! A pair that I first got at Walmart got quickly taken back and exchanged. They went THUMP, THUMP,THUMP in my dryer and I couldn't stand the noise. The soft ones are quiet.
