I'm with S
mallpatch with regard to drawing back the finish before resorting to stripping it. Which you can do. But then you are also going to restain and wreck what you like. Dull oil finishes are cheap work. The skill is in working a varnish then and now.
Abrasion index is: pumice and water-most abrasive, then pumice and oil, rottenstone and water, then rottenstone and oil. You DO NOT apply with a rag. Use a tooth brush in a scrubbing motion then wipe clean. Whether carving or broad open surfaces. Use the abrasion you need , but start at the bottom, the least abrasive first.A little wax after is fine.
