I keep my Neatsfoot oil in a spritser that was left after the bathroom cleaner fill ran out I only apply neatsfoot to the back/flesh side of the leather.
Lay the strop back side up on an old tea cloth then spray a light coat over the strop evenly. no rubbing required.
On the working face I use a variety on options depending on the strop being dressed.
One method I like for very textured russian strops is rubbing a bar of saddle soap direct onto the leather. I then buff the strop vigorously with the palm till the suface is matt. Dont over do the saop though.
