While Judenfrei referred merely to "freeing" an area of all of its Jewish citizens, the term Judenrein (literally "clean of Jews") was also used. This had the stronger connotation that any trace of Jewish blood had been removed as an impurity.

 Usage in Israeli–Palestinian conflict
In the Israeli-Palestinian conflict, a fear among many Israelis which has been reflected by Israeli government officials such as Benjamin Netanyahu is that the proposed removal of Israeli Jewish settlements in the West Bank according to the wishes of Palestinian officials is tantamount to rendering areas of Judea and Samaria as Judenfrei, or clean of Jews.
