Cleaning/treating your leather Chanel bags

  1. Does anyone spray/treat their leather Chanel bags? I've never done it in the past with any of my classics but I've just gotten a new Coco Cabas in black leather and was wondering if it's something I should do. Let me know your thoughts.
  2. I have heard that Chanel recommends Vectra spray.
  3. Where can you get that spray from?
