I had white bar tape on my Fuji. Since we are planning to sell the bike, I would like to clean the bar tape. The tape is in good condition and a buddy did an amazing wrap job on it (regular tape felt as good as my new gel tape), I hate to replace the tape. He moved to PA, I can't get him to re-wrap the bars.

Anyone got an idea how to get some of the black/grey off the white tape? Anyone know why they insist on using the hideous white tape?
