What is apple guard? a protectant or cleaner? I have always been told not to use anything on the bags. My SA says to "Give them Life" He's oh so French. "Vuitton is made to be used, any mark or scratch is a result of you and your experiences, which makes the bag even more personal". Then he gave us the story of in France "Broken in is a much better look, it gives the piece history, women will give their new bags to little children to play with in the garden, so the bags will look like they have been around." (Imagine that in a french accent) My husband couldn't keep a straight face! I heard that a decade ago and took it heart and use all my bags as normal. Anytime something leaves a mark we just laugh and go "it just got some more life"
