I would agree with previous answer. We've used Danish oil on just about all our different exposed wood in our Victorian house (pine doors, teak kitchen work surface, etc) and it looks fabulous.
It soaks in and so protects the wood from water, fingers and general wear and tear. You'll need several coats to build up a decent finish and it will need to be reapplied occassionally in the areas that received most use (i.e. edge of door where your hands open and close it) as it does wear down a bit over time. But we're talking ages here!
Try it on a small inconspicuous area first if you're not sure.....but I've found it to be a hard-wearing, protective and attractive finish.
