ELI5: How do dryer sheets remove static?
gpt
When your cloths tumble around electrons can get stripped from one item and placed on another item giving the two pieces of clothing an over all positive or negative charge. If they do differ you get static cling. Since clothes are not good conductors of electricity the charge can last for quite some time. 

Dryer sheets are just a fabric sheet impregnated with fabric softener, fabric softener is positively charged.  When the sheet tumbles around the softener comes off and gives the clothes an overall positive charge, preventing opposites and thus cling . This is the same reason many people use fabric sheets to help dust around the house. The positive charge left behind helps prevent dust build up.
