Indigo rubbing off on shoes

My sneakers have a beige suede tounge that's now blue from the indigo of my jeans rubbing off on them. Even if I cuff them, the inside of my jeans is still enough to rub off.

Any cleaning solutions on how to get rid of this indigo on suede? I haven't washed my jeans yet... should I soak the cuffs in hot water to get rid of some of the extra indigo?

Thanks Brian. The eraser got rid of about half of the indigo. It's a start I suppose... I'll get started on taping up the inside of my jeans. Can I draw little red lines on them, and roll up my cuffs?
