I hope she takes Saddle On-line's advice. I've cleaned hundreds and that's what I would suggest also. English saddle leather isn't the same tannage as western saddle leather. A Barnsby is of an excellent tannage. I rode many miles in some that were 30 years old and the only thing that was used was Propert's Glycerin soap (same as Belvoir) and water. We worked up lots of suds with a sponge and applied that. Never touched a drop of oil or cream or conditioner to them. It has been my experience that once too much cream/oil/conditioner has been added it is very difficult to remove. Try the suds and allow them to sit for a minute then blot with a squeezed out sponge or a damp cloth, rinsed and squeezed almost dry. Don't wipe as I think the leather has had enough rubbing and may make the surface fuzzy.
