The family, lead by the father in the light of a candle, searches for leftover leaven (usually the mother has left some crumbs for them to find). They take care to search in cupboards and drawers. Using a feather they brush any crumbs onto a wooden spoon and place them in a bag or piece of cloth.
The next morning the family takes the package of leavening outside and burns it.
The father then recites the final renouncing of the Chametz:
In this traditional Jewish ceremony we see the family cleansing their home from leavening/sin and then asking the Lord's to overlook any which may remain. We know and acknowledge the impossibility of removing all leaven/sin but the attempt should be made.
