Just stumbled across this post after my walk to the post office... it's 91 degrees out.... my shoulder strap now has a nice stain on it from my arm pit. I'm heart broken. I DID treat this bag with Lovin My Bags so hopefully the mark will fade as it dries. Fingers crossed! As for my sweaty hands and my Alma... I usually end up carrying it on my arm so I have my hands free so my handles still look good..... for now. <sigh> So glad to see I'm not the only one with this problem.
Please let me know if LMB worked. If it didn't work try wiping the entire bag with a clean damp cloth ASAP- if that doesn't help use cleanser and lightly use magic eraser to clean. Don't over scrub. I used LMB on my dueaville but still got a water spot somehow so I had to use LMB cleaner and magic eraser to clean (it removed it) and then condition it.
