Boiled linseed oil is OK, but it tends to take a long time to dry and slowly turns black.
Got it backwards. the boiled linseed oil is treated and dries quicker. The raw takes longer to dry and I prefer it but either will do and both will darken over time.
Boiled linseed oil... slow to dry.
Raw linseed oil... really, really slow to dry.
And just for the record, boiled linseed oil isn't boiled any more -- it has heavy metals added to speed the drying time. So it's fine to use on rifle stocks and furniture, but don't use it on salad bowls, or anything else that comes into contact with food.
To
renew a shabby, dry-looking oil finish, sand lightly, clean off with mineral spirits, saturate the wood with oil, and wipe it off very thoroughly -- don't leave the surface wet. Let dry completely (for boiled linseed oil, a week is good). Wipe down with oil again, wipe off, let dry... repeat until you're happy with the surface.
To
maintain an oil finish, wipe the surface with just a few drops of oil, wipe it off, let it dry. Unless it's getting a lot of use or exposure to weather, once a year is plenty for a surface that's basically in good shape.
