How do I clean my Andy Warhol tote?

I got this bag a while ago and have been using it for school. All the wear and tear is really starting to show up and I need to clean it BADLY, but I don’t want to mess it up…. here it is: http://cgi.ebay.com/ANDY-WARHOL-Loop-NYC-HAPPY-BUG-DAY-Tote-Bag-NWT-Sale_W0QQitemZ260365942661QQcmdZViewItemQQptZUS_CSA_WH_Handbags?hash=item260365942661&_trksid=p3286.c0.m14&_trkparms=72%3A1494%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318%7C301%3A1%7C293%3A1%7C294%3A50

A spray like oxyclean? Or put it in the wash without the accessories though when I did that to one of my canvas totes it didn’t do much.
If you scrub it use a scrub that isn’t coloured dark like the green and yellow ones cause the green stuff will just come off all over your bag.
