Butter on paper

I would like to remove some very freshly deposited butter from
paper. The paper is in a small sketchbook with a sewn binding. The
book is filled with drawings worked in graphite, ink and
watercolour. The butter is on many pages, along the spine, at one
end of the volume. It often occurs within the image area. The butter
seems to have caused some of the watercolour to migrate. The
drawings are all quite recent.

I'm guessing that the success of the treatment will be best if it is
undertaken soon. Does anyone have experience or suggestions that
might be helpful in addressing this problem?
