Do not unworthy sinners need to be cleansed before receiving?
No one can ever be fully worthy of God’s supernatural graces. The Eucharist is not a reward for good behaviour, but the VERY SOURCE of goodness. Small (venial) sins are wiped-away when we receive Communion or any of the other Sacraments. Only mortal sin ruptures our relationship with God, to the degree that we cannot receive His sanctifying grace without prior forgiveness.
