The lining is washable. You can pull it out and wash it with soap and water, but that requires a lot of rinsing and it is hard to keep the leather dry. If it isn't too dirty, I use a mild spray cleaner that doesn't require rinsing. I wouldn't attempt to polish the brass - it usually gets worse on these bags. Coach943's suggestion to treat the exterior with Obenauf's sounds good.I just acquired a pre-loved Legacy 10328. It's in wonderful condition, no water stains, and not a lot of fading. Because it is pre-loved I would like to freshen it up. I've read the many posts regarding the dyed nature of the vachetta leather of some of the Legacy bags and cleaning it with vinegar. Would any of you suggest a full wipe of the bag (leather and brass) with vinegar and then using some sort of moisturizer and water protectant on it? Also, how do you clean the interior? There aren't any stains, but once again, just want to clean it prior to using it. Any help would be appreciated.
