Hand Sanitizer on Shabbos or Yom Tov (Passover) Status: May I use hand sanitizer on Shabbos and Yom To? Rav Schwartz ZT”L said that using a hand sanitizer such as Purell on Shabbos and Yom Tov is no different than using liquid soap; Iggeros Moshe (OC 1:113) holds that this is not permissible, but many Poskim are of the opinion that it is permitted. Rav Schwartz ZT”L accepts this latter approach.
