adios star campeggio/AS in general-will it get too dirty??

I have an AS Zucca that I used on a trip to LA a few months back. It did have a little dirt on it after I returned, but I was able to clean the dirt off with warm water and a little Tide.
 
i have an AS ciao and the only time i wore it was on a day trip to Monterey, CA. it wasnt until recently that i noticed the back of the ciao had a FAT blue streak underneath the short zipper in the back which made me realize that it was probably rubbing up against my jeans/clothes the whole time, leaving that streak as well as a few other smudges. made me really mad, but thankfully Mr. Clean came to the rescue w/ the Magic Eraser...didnt take all of it off completely but at least its not as dark anymore...

so yea, dont think i'll be buying anything else in adios star...
