Just got my white Lorca and my bittersweet Gaza and there was a paper in there saying something about treating the leather to prevent water spots, and cleaning the leather occasionally. Would Apple guard be the best for this? Is it ok on white leather? I've never treated a bag before but now I have some nice ones (RM MAM, BE Love me, LP Dylan) plus a really light tan one I found at Macy's. Should I treat all of them or only certain bags? I just spray it on in light strokes like when you do shoes right? How often do I need to clean and condition them? And if the white bag gets dirty (which Im sure it will), does the AG cleaner work well or should I try something else?
