While I have a few leather care products that I'm happy with, I'm always curious to try different products. And since I do some custom leather work, I like to have a variety of brands that I can suggest to or dissuade people from using.
Currently I use Fiebings' saddle soap
as a once- or twice-a-year tack cleaner (I prefer the bars or paste, but don't mind the spray on either. I'm just a perfectionist.), and in between, I like Weiman Leather wipes
to clean up after a dusty, dirty ride.
I really *love* Australian Stock Saddle Co.'s Leather Keep
, especially for smaller items (halters, reins, boots), but I'm not overly impressed with using it on saddles (it doesn't seem to work into very thick saddle leathers very well.)
The only time I use neatsfoot is on extremely old, cracked leather -- like the harness I just dragged out of my grandpa's barn that's sat for almost 100 years.
And even then, I'll only use 100% pure oil, never Lexol, and just enough to bring the leather back to life; then it gets a good washing.
I've yet to decide on a neatsfoot-alternative that I like.
