Anyone have any home made ways to clean old leather?

Charlie's grandpa brought over the old baptism outfit and shoes that Charlie's dad wore to his own baptism. I've decided to hand wash the outfit and blanket in wool lite, but does anyone know how to clean really old leather shoes? They're white.. everything I'm finding online is all about shoe brushes and leather care stuff and sounds expensive. Not that it's not important, I just would rather do something home made and cheap if I can.

Would a toothbrush work? With some soap or something? Maybe put some oil on them? I don't own anything leather so this is a new one.

    I'm not sure but I think the outside f a banana peel works
