– Q. Can one use on Shabbat spray cans or aerosol dispensers for removal of bad smells in a bathroom or kitchen?

A. Some Poskim question the use of spraying devices on Shabbos, nevertheless, Mori Horav Moshe Feinstein Zt”l, and other Poskim including the Minchas Yitzchok ruled that because the scattering is not caused directly by human blowing or wind force, but rather by the pressure in the can dispenser, it is not similar to Zoreh and it is permitted to be used on Shabbos L’chatchila.

On question 2220 regarding if one can use suntan and insect repellent liquid oils and lotions during Shabbos and Yom Tov, for skin protection when walking outside during the summer, or if one can also spray the new aromatic insect repellent on clothing, we wrote that Poskim permit using suntan and insect repellent liquids, oils and lotions, when they are thin, of low viscosity, and of flowing consistency. They also should not be for medicinal use. (Piskei Teshuvos 327: 1).

Horav Shlomo Miller’s Shlit’a opinion is that it is permitted to spray repellent on clothing also, even if it has some aroma, since the main intention is not to impart fragrance, but to repel insects
