my advice: don't use the cleaner. It's not dirty!! In fact, I never use the cleaner. Only the conditioner. And I only use that when it seems dry, if ever.
I've never used the spray, but that's a preventative measure, if you want. I've heard positive things about it, and I do have it (I've just never taken the plunge). I guess I'm just too scared to change the leather, and I've found that the conditioner followed by good buffing never changes it at all, but keeps it supple. Again, though, only when needed.
contrats!
