Reference for Zevachim 11:6

כְּלִי נְחשֶׁת שֶׁיָּצָא חוּץ לַקְּלָעִים, נִכְנָס וּמוֹרְקוֹ וְשׁוֹטְפוֹ בְמָקוֹם קָדוֹשׁ. נִטְמָא חוּץ לַקְּלָעִים, פּוֹחֲתוֹ, וְנִכְנָס וּמוֹרְקוֹ וְשׁוֹטְפוֹ בְמָקוֹם קָדוֹשׁ:

[If] a copper vessel went outside the curtains, one brings it in, and scours it and rinses it in a holy place. If it became impure outside the curtains, one punctures it, and brings it in, and scours it and rinses it in a holy place.
