Q. If your hands are dirty, are you supposed to wash your hands with soap first and then wash with the neggel vasser cup, or vice versa?
A. Horav Shlomo Miller's Shlit'a opinion is that it is not necessary to wash hands first for washing Neigel Vasser, as it would be for washing before eating bread.
Rabbi A, Bartfeld as advised by Horav Shlomo Miller and Horav Aharon Miller Shlit'a
