I use Lanolin/white spirit as a dressing for my horse hide strops. "Anhydrous wool fat" is the chemists name for it and is what Rolls Royce use as a dressing for their car upholstery. I started using it on my WW2 Irvin flying jacket but then the light bulb came on, " I could use this on that old Horse hide strop couldn't I!" It worked a treat. Small amounts as usual are the best way to use a dressing.
