With which hand should the Tefillin be removed?
Which hand should a lefty use to remove his Tefillin?
One whose left hand is his stronger hand, should use his right, weaker, hand to remove his Tefillin. This applies even if he writes with his right arm and therefore wears his Tefillin on his left arm.
 Admur 28/5; M”A 28/3; Elya Raba 28/4
 Maharash of Lublin, the Rebbe of the Shlah brought in Emek Habracha 2/15; Shlah Miseches Chulin
 The reason: As the left hand is the weaker hand, and by using it one shows that it is [emotionally] difficult for him to remove it, as in truth its Mitzvah applies throughout the day, and it is only due to that we do not have clean bodies that we remove it immediately after Davening.
