- Question: [Sunday 2nd Menachem Av 5781]
The hinges of the door of the shul are making a very squeaky noise which is quite annoying and disturbing people who are Davening. May I pour oil onto the hinges on Shabbos in order to get rid of the squeaky?
It is forbidden for you to do so due to the prohibition of Tikkun Keli
