i'm so excited to have purchased this bag! i got it on thursday and i am so proud to be an LV owner! so my question is: what to do to prevent stains and care for it correctly? i have searched the boards about the apple garde spray and conditioner. and i have ordered them online. so now, how OFTEN to apply them? i know i will use the spray right away. and i'm guessing this is a one-time spray? how about the conditioner? how often to apply it? thank you so much! any suggestions/advice on taking care of this bag will be very much appreciated!
