Instead of using expensive costly sheet fabric softeners in dryers, buy a budget liquid softener. Moisten an old face cloth with the softener and put it in the dryer with the clothes. Use on every load. It will reduce static electric build up.
Or on delicate or light fabrics, put a wet towel in with them. The towel will take longer to dry than the garments. Static electricity is caused by over drying and this will eliminate the problem.
