Question about conditioning a leather jacket. I bought a leather jacket about?

two years ago and haven't worn it yet. I wanted to condition the leather so it doesn't dry or crack. I used a lotion made by Kiwi and it was cream colored and sticky. I put it on with a small paint brush. When I went to rub it off instead of leaving the coat dark brown like it was originally, it has a cream color haze on it and the seams are sticky. How can I get the sticky off and not ruin the leather? I know I can't use water or I'll ruin it. Will vegetable oil work? Any other suggestions?
