Q. Can one use a tissue paper towel or a napkin used for drying ones hands after washing for a Shabbat meal, to further clean and dry hands, mouth or nose, during the meal, when it still is wet and it may involve prohibited Sechita or squeezing?
A. Poskim usually rule leniently on the use of disposable napkins and tissues, since they are not reusable and one does not benefit and care for the prohibited s’chita or squeezing. (Igrois Moishe O.H. 2: 70, and others).
Horav Shlomo Miller’s Shlit”a opinion is similar.
