Clever, or not really?

From the blog, Apartment Therapy, comes this tip of using a walnut to buff out dings in wooden furniture. But the comments complete the story: first of all, since it's really the oil that's doing the job, any number of nuts can be used to the same effect (locals here in Texas may want to use pecans as a point of domestic pride), but I think the bigger point to be made is that people with nut allergies may be in danger of such furniture. So, perhaps simple mineral oil would suffice.
