First of all, carefully unscrew all the cabinet doors at the hinges. Use a proper screwdriver. If you’re only going to retouch the doors, you can leave the hooks attached to the cabinet boxes. Empty the cabinet drawers and remove them. Also, remove all the knobs and pulls. Electric drills or screwdrivers can make this go a lot faster.
Next step, clean the doors you have removed. Scrub the surface of doors thoroughly with a robust degreasing cleaner, like trisodium orthophosphate (TSP). Use a kitchen scrub-sponge and a toothbrush to get rid of grime collected in grooves and corners.
If you can’t get all the dirt off the first time, try another time. Unless the surface is immaculate, the new finish won’t adhere to the doors that well. After finishing cleaning, Rinse with water and allow them to dry.
Now, it’s time to fill in holes or cracks. With times there will be holes, cracks, and dents within the cabinet doors and drawers. Before you proceed any further, make sure you cover all the holes and cracks with the carpenter’s wood putty. Let the putty dry, then continue.

After cleaning all the dust, apply the wood stain. It’s best to use a fine-bristle brush, generously apply the stain to the surface of the doors and drawers. Wait for 5 to 10 minutes, then wipe it off with a clean, lint-free rag. We await the stain to dry.
Finally, apply the varnish. It’s best to wait about 24 hours for the stain to dry before varnishing. If you’re doing each side of the doors, wait about 8 hours before turning the doors over and marking the opposite side. Apply a minimum of two coats of compatible varnish or polyurethane. You can use either a sprayer or a high-quality brush. Sand the cupboards lightly between layers for a smooth and durable finish.
