I love my Barenia Kelly! I bought it pre-loved and the previous owner had put some rubs on the piping, but in the three or so years I've owned it I haven't inflicted any damage on it. It's a daily wear bag for me... it goes on vacation, to bars, to work, to the pool, in rain, etc. It's been soaked, spilled on, scratched,lip-glossed, Roshi has put his little nose on it.... it looks better than when I first received it. When something gets on it I dampen a paper towel with water and give it a rub down. When the spills are bad (like the mimosa that spilled all over it on Sunday) I saturate the leather pretty thoroughly (kind of scary looking) and it dries evenly and gets rid of any spots.
Here is a super quick phone pic of my very used kelly:
