Q. I bought a new toaster, but since during the pandemic days it is hard to find a mikva for keilim (vessels), can I meantime just place some aluminum foil on the racks and use as is?
A. You may look for a nearby lake or river to immerse your new toaster racks or even sell them or give them as a present to a Gentile.
Disposable aluminum foil does not require tevila (see Minchas Yitzchak (5: 32), Igros Moshe (Y. D. 3: 23).
Therefore, Horav Shlomo Miller’s Shlit’a opinion is that, covering the racks with aluminum foil is permitted as a temporary option.
