A utensil which was used with gebrokts food may be used for non-gebrokts. [Natei Gavriel Pesach 3:37:13:footnote 26]
Nonetheless, the custom of some is to have separate utensils for gebrokts, and only use such a utensil on the last day of Pesach.
Shuni Pesach page 160, Ohr Yisroel 15:page 145.]
Some permit food which was
cooked in the same pot with gebrokts foods. [Tzitz Eliezer 12:53:2.]
