Tevilas Keilim: Clearing The Confusion

The daf yomi cycle finished Mesechta Avodah Zara over Pesach. The end of the mesechta discusses the biblical mitzvah of tevilas keilim. Therefore, it is appropriate to point out some of the biggest myths related to this mitzvah.
Myth # 1: One may temporarily use an item without tevilah.
This is clearly not true. One may not use a utensil that is obligated in tevilah even one time prior to tevilah. This myth is born from the fact that there is a firm basis to permit using disposable aluminum pans without tevilah. However, while a disposable aluminum pan can be used without tevilah, a non-disposable pan cannot be used even temporarily without tevilah. This often comes up on camping trips where inexpensive grills are purchased. Perhaps the cheapest of grills—the ones that sell for nine dollars and use charcoal—are considered disposable; however, one cannot use the metal grate for a non-disposable grill even temporarily.
