Spider Climb on Grease? poll

Can a wizard use Spider Climb on a Greased surface?

Looks to me like "yes", but having to make Reflex saves as normal for the grease spell. The spell says you can climb walls "as well as a spider does"; spiders have a Climb a speed, but that doesn't say anything about being immune to slippery surfaces or Reflex-save based spells.
