Halocho #956 - Chanukah leftovers

Oil that was put in the Chanukah Menorah and was not burnt, as well as wicks that were used and candles that didn't burn fully should be burnt after Chanukah.

Since they were set aside for the Mitzva of Chanukah they cannot be used for any other purpose.

If one had the explicit intention to use the left-overs, then they need not be burnt.
