I have had my ipad2 and smartcover since the day they came out (~7 months) In that time, my cream color smart cover has become only what you could call dingy. I've tried various cleaning methods from expensive leather cleaner to Pledge. Nothing works . So I thought if I could change the color of the cover to black, I would have less issues with its appearance. It looks like a dirty bathmat. Does anyone know about changing the color of leather? Or have any other ideas of improving the appearance of this eyesore?
