Yup, neatsfoot is what i use before i send anything out!
Decent leather should be firm butN OT cardboardy hard, neither however, should it be REALLY soft..
Use a cloth well wrung out in warm water, to get off any grease and muck.... on horse tack i use a knife (non serrated) to scrape off any grease, then use a clean well wrung out, nearly dry cloth on some saddle soap.
If you have an item stitched iwth traditional linen thread though, be careful as water and oils can rot the thread!
