Your quite right and i do that all the time. In this case it wasn't necessary since the mineral oil would be left behind anyway during distillation. hexane washing would have been an extra step. If i were using the solvent without distillation, then mineral oil contamination would indeed be a greater issue and hexane washing would be necessary.

As far as I've been told, sodium is pretty terrible at removing oxygen from solvents. I've always ended up freeze-pumping all my solvents before doing air-sensitive chemistry.
