 Kama 4/18
 Between the graves is explained to refer to a cemetery. [M”A 4/20 in name of Teshuvos Mahril 23; Kol Bo; Chayeh Adam 2/5; Kitzur SH”A 2/9; M”B 4/42; Gesher Hachaim 16/8; Kaf Hachaim 4/76; Piskeiy Teshuvos 4/25]
Opinion of Admur: The Rama 4/18 writes “one who walks between the dead.” The M”A records that this means a cemetery. Admur does not record either the wording of the M”A or the Rama rather he writes “between the graves”. Vetzaruch Iyun if there is any practical ramification between the graves or a cemetery.
 M”A 4/20 in name of Teshuvos Mahril; This applies according to all. See Halacha 2 in footnotes.

 Ishkavta Direbbe p. 107
Opinion of Admur: The Magen Avraham 4/20 defines “between the dead” to mean a cemetery. Thus according to him it seems that one must wash the hands even if he was not near the actual grave. However Admur omitted this explanation and rather wrote “between the graves”. Vetzaruch Iyun if there is any ramification between this wording and the wording of the M”A.

 Ishkavta Dirrebe p. 106; Beis Rebbe “Harav Hakadosh Miberditchiv”; Piskeiy Teshuvos 4/25
The Alter Rebbe visited the resting place of Reb Levi Yitzchak of Berditchiv after he passed away. After Admur left the grave he was offered water to wash his hands and Admur replied that he does not need to wash his hands as the gravesite of Tzaddikim do not impurify.” [Beis Rebbe ibid] Practically this is the custom of the Chassidim not to wash hands after leaving the resting site of the Rabbeim, as was seen amongst Chasidim that visited the burial grounds of the Rebbe Maharash and Tzemach Tzedek [which are positioned in the entrance to the cemetery in Lubavitch]. Likewise the Rebbe Rashab would not wash hands after visiting the gravesite of his father the Rebbe Maharash. The reason for this is because although even the grave of a Tzaddik gives off impurity it nevertheless is a holy place and does not give off the evil spirit, and the entire purpose of washing the hands is to remove the evil spirit. [Ishkavta Direbbe ibid]
 Thus those that visit the Rebbe’s Ohel in Queens must wash hands afterwards being that it is within a cemetery. This was also the Rebbe’s custom.
