Remove excess oil from the surface with a clean cloth. Let the oil absorb well on the surface and leave it for some time to dry. It may take 24 hours to dry. Now rub the surface with steel wool.
After drying, apply two more coats:
Make sure the oil mixture dries well on the surface. Now apply another coat on the surface and let it dry. Repeat this process. And sanding with steel wool.
