WASHING DISHES
6.a. On Shabbath,
1) a) one should refrain from pouring hot water from a keli rishon onto soap in order to dissolve it, but
b) one may put the soap (which is boiled during the course of manufacture) into hot water in a keli sheini.
2) a) Liquid soap too may be put into hot water in a keli sheini, but
b) hot water should not be poured onto liquid soap from a keli rishon.
6.b. On Yom Tov, bars of soap and liquid soap, which are boiled in manufacture, may be put even into a keli rishon standing on the fire.
6.c. See also paragraph 14b2 below and Chapter 14, paragraph 16.
7. It is the practice to wash dishes with cleaning materials even if they produce a lather, since this is not in itself an infringement of any prohibition.
