If you choose to use neats foot oil be sure it says “100% pure” and “oil”, not “compound”. Compound has other nasty things like silicones that do more harm than good.
I also used good ol plain shaving cream to soften my baseball glove(s) during break in. Like Barbasol. Avoid those fancy brands.
Then maintain once a year or so with a light application of neats foot oil.
Hope this helps. Others’ mileage may vary.
Regards.
