There are many good ways to put the shine on a briar pipe, and for years I took the hot pipe and used face oil. Your nose is especially rich in pipe polishing oil. But, people do tend to laugh at you doing that.
Let’s say you’ve finished deep cleaning. Your pipe looks, smells, and tastes new, but it’s dull.
It’s really the same as a gun stock or fine piece of furniture now.
You can put a finish in the wood (oil) or you can put one on the wood (mostly waxes, or other clear, hard finishes).
I’ve been known to oil, then wax a pipe.
But now that I’ve found grapeseed oil for briar and Obsidian oil for stems, it keeps me occupied polishing them.
