Washing machines wash the clothes twice. Is this sufficient to cleanse the clothes of najaasah?

Praise be to Allaah. 

We put this question to Shaykh
‘Abd-Allaah ibn Jibreen (may Allaah preserve him), who answered as
follows:

 The ruling has to do with
the najaasah itself. Once the najaasah is removed from the clothes, they
become taahir (pure). Shaykh al-Islam Ibn Taymiyah said that there is no
specific number of washings required for najaasah to be removed.

 And Allaah knows best.
