Review - Bag from Xquisis

My white motorcycle bag from Xquisis has arrived!! I love it but there are some stains on it. Wonder if I should ask for an exchange. But I really really want to bring it out for Christmas! I managed to clean some of the stains off using wet tissue but some are still visible =.=

Can see the stains?

More stains =( 

Compare it with my black bag. Think it's easy for white to become stained.
