Leather duster.

[Blogman]

I left my duster in in the schoolhouse over the summer/fall and have cleaned it up as much as possible. Now I need to condition it cause it's rather stiff. I have tallow, gun oil, coconut oil, beeswax, etc.. but nothing in the house for leather as needed. Anybody have an ol' school way for this? Could someone give me some tips/hints/advice as to soften it up?
Needless to say I'm so broke I broke my broke, hence the tips. Thanks

I use mink oil on my boots now. I used to use deer tallow. I just hand rub it in very aggressively and wipe off excess. Kept my boots quite supple and flexible.

Have no mink but do have bout an oz of mutton tallow. Ya think that should cover a full duster?

Skidmore leather conditioner is the best stuff I've ever used on leather and it's cheap
