Hello everyone! This is my first time to post a new thread so please be kind ! I have a few LV pieces and I was wondering if Apple Guard is supposed to be used for new bags only? I am getting Apple Guard from a friend flying in from the US and was wondering if I can use it on my Mono Speedy 30 and my Neverfull MM, both of which are about 5-6 months old. I'm particularly concerned about my Speedy's handles since they're starting to get a little dirty. Should I use magic eraser first and then the Apple Guard? I've tried to read up on the other threads but I haven't seen anything specific as to when Apple Guard can be used apart from using it on new bags to prevent it from getting dirty (though it will still acquire patina right)? Tips and comments would be greatly appreciated! Thanks in advance!
