If you have shallow scratches or nicks, hide them with a stain-filled touch-up marker. Dab on the stain and wipe off the excess with a rag. But beware: Scratches can absorb lots of stain and turn darker than the surrounding finish.
So start with a marker that’s lighter than your cabinet finish and then switch to a darker shade if needed. For deeper scratches, use a filler pencil, which fills and colors the scratch. Or, try using a walnut to remove scratches in wood!
