hmm. i googled on neatsfoot and here is what i found.
"Neatsfoot oil fills the capillaries in the leather and prevents the exchange
of humidity- it also makes the leather 'sleazy', invites rodents and dogs to
eat it, pulls dirt out of the air and crusts it to your material.
Neatsfoot is used to refurbish leather that is filled with horse sweat-
salty, crusty, and stiff.
I prefer a 'shoe creme'- sometimes a little pure lanolin- never used saddle
soap or neatsfoot...
