sunning a cutting board to remove stains

Until recently, I was uninitiated as far as the pomegranate. A friend of mine came over to coach me through my first pomegranate experience, and for the mist part it was awesome. But I neglected to clean off my cutting board until the next day, and it was covered in pomegranate-purple stains. I will often put laundry in the sun to get stains out, so I thought I would see if bamboo cutting boards respond the same way. Here goes nothing!
