Restoring silk line

Got in an old reel, and it was loaded up with silk line. The line is
definately silk, and in good condition. It is not tapered. It has a memory
from being tightly wound towards the spool, so part of it is a fairly curly.

I was thinking:

Soak the line for an hour in a mild TSP solution

Wipe down with a coarse cotton cloth

Hang from the shop ceiling joists to dry


Treat the line with a dilute tung / boiled linseed oil mixture


Question? - Should I stretch the line while drying? I have
plenty of room to stretch the whole line out.
How taught should it be?

Is there a modern alternative to mucilin? Something readily
available at the hardware store or found around the shop? Or easy to make,
like a mix of turpentine, beeswax, and parafin, for example.


I'm especially interested in trying this line out, to see how it compares to
the new Sylk lines. I have a WF6F Sylk on order that should be in this
week, and a 6 wt. ("D or HDH") 8'-6" rod with small guides that I really
like.

Any silk line reconditioning tips appreciated.
