All,
Is it possible to help old cloth-covered power cords keep their
flexiblity? Is there anything that can be applied to rejuvenate the
cotton covering to prevent fraying?
rgds,

I have actually not seen the cloth coverings degrade over the years other
than from mechanical abrasion. You can try washing them in Woolite (no joke!)
to get them nice and clean, and then just treating them carefully.

Abrasion will kill them very quickly, and once they start to fray they will
just get worse and worse. A little clear lacquer on damaged parts can keep
the damage from spreading.

A lot of those cords were made with natural rubber insulation and then an
outer cloth jacket. The cloth usually outlives the internal insulation
which becomes hard and crumbly. When this happens, the cord MUST be replaced.
