On my way to my German class last week, I bought a snack and a bottle of Coke Zero @ the train station. I was having a hard time juggling everything when my unopened coke bottle started to leak! I totally freaked out. But most of the spilled coke just rolled off the Mini Lin canvas. Whatever remained on the canvas beaded up, which I dabbed away w/ a napkin immediately. I throughly examined the area, and there was no stain whatsoever. But for good measure, I wiped down the whole bag w/ a slightly damp towel when I got home later. I haven't treated the bag w/ anything so far. But I do plan on spraying it w/ some Shining Monkey in the future.
