Hi there, What do you guys use to clean the leather on Mono bags? I've sprayed it with leather protector, but I see little spots of dirt that I'd like to spot clean. I have a Lockit, so there is the vachetta to worry about. Would the Coach leather cleaner/conditioner be okay? Also, how often do you spray? I've just done the initial spray, dried for an hour and then another spray. I don't want to over do it. Thanks!
