My favorite leather cleaner conditioner, that I
have used on everything from basic leather tack, to my good leather show harness
is Effax cream.(not the liquid) Here is a link to some on ebay. Not in all
tack shops. When I visit So. CA, I always pick some up at Broken Horn. I love
this stuff. And my hands always feel really nice afterwards too. It runs between
$10 and $13 most places.
