Remove all doors, drawers and drawer fronts from the cabinet framing. Set aside hinges and screws if you plan to use them on the refinished cabinets. Unscrew and remove all door and drawer handles. Recycle them if you plan to use new hardware, or set them aside if you want to reinstall them.
Spread out the cabinet doors and drawer faces on a large, flat surface with plenty of ventilation. A patch of grass or an open garage are suitable. Lay out a drop cloth or old sheet to protect the surface underneath.
Wipe the cabinets doors, drawers and framing clean with a damp cloth. If necessary, use a mild wood cleaner to remove difficult spots. Let them dry.
Sand the doors, drawer fronts and framing with 120-grit sandpaper. Work with the grain of the wood in smooth, even strokes. Once the finish has been removed, go over the exposed areas lightly with 220-grit sandpaper. The wood should be free of scuffs and rough spots.
Vacuum the wood with a shop vac or vacuum cleaner extension to remove sanding dust. Wipe all grooves and surfaces with a clean soft cloth to remove any remaining dust.
Apply your choice of stain to the doors and drawers with a paintbrush or clean cloth, working the stain into the grain of the wood. Always work in the direction of the wood grain. Wipe away excess stain with a cloth. Keep the doors flat while you stain them to prevent drips.
Stain the exposed wood of the cabinet framing the same way you stained the drawers and doors.
Add a second coat of stain to both the doors and the framing, if desired. A second coat of stain will yield a darker finish. Follow the instructions on the can to ensure proper drying time between coats.
Apply a clear finish to the surfaces once the cabinets have had time to dry thoroughly.
Reattach the doors and drawer fronts. If you wish, replace the old hardware with new hardware as a finishing touch.
