What is a good leather conditioner or moisturizer that works on various colors and leathers without discoloring them? Would something like Bick 4 fit that bill or is there perhaps a better alternative?
That's my solution.I use Saphir Medaille d'or Rennovateur on items that don't need water resistance, and have a can of Obenauf's lp for say boots etc
Be careful with some leather conditioners on dress shoes. While they do not discolor the leather, they make it darned near impossible for the leather to hold any kind of shine/polish. Bick 4 has worked well for me.
