Responsa for Zevachim 192:12
מ"ט דרבי יהודה מדאיצטריך אותה למעוטי תרומה מכלל דקדשים קלים טעונין מריקה ושטיפה ור"ש אמר לך אותה כדאמרינן
What is R'Judah's reason? - Since 'thereof' is necessary to exclude terumah, it follows that lesser sacrifices necessitate scouring and rinsing.<span class="x" onmousemove="('comment',' For if they did not, then terumah, whose holiness is certainly less than theirs, would obviously not necessitate scouring and rinsing, and the Scriptural limitation would be superfluous.');"><sup>21</sup></span> And R'Simeon?<span class="x" onmousemove="('comment',' How does he rebut this?');"><sup>22</sup></span> - He can answer you: 'Thereof' Intimates what we said elsewhere.<span class="x" onmousemove="('comment',' That only a fit sacrifice necessitates scouring and rinsing, but not an unfit one; v. supra 93a.');"><sup>23</sup></span>

A. In France I witnessed a great controversy over this matter. But, at the time, I failed to inquire into the reasons of both those who permitted and those who forbade the use of the pot and its contents. I also discovered that Ri forbade the use of the pot and its contents, probably for the reason that the drop of milk first rendered the pot unfit for use, and the pot, in turn, rendered its contents unfit for use.

A. Rabbenu Samson permits its use while Ri forbids it. Ri bases his opinion on the fact that a drop of milk does not spread over the whole pot, and since the part of the pot affected is not sixty times the volume of the milk, the milk is not neutralized. Therefore, even according to Ri if one could gage the volume of the milk and find a ratio of one to sixty to the volume of the part of the pot affected, the milk would be neutralized. In any event, if the loss be an appreciable one, or the enjoyment of the Sabbath or a holiday be involved, one may be lenient, in view of R. Samson's opinion.
