Drop The Gloves has developed a proven system to remove those unwanted autographs, personalizations or stray markings from your game worn jerseys. Our system is safe and will not harm the jersey. Please be aware that this system only works for autographs or markings on the jersey material itself and does not work on twill numbers or logos.

I've never tried this and it does seem risky...

Adrian Dantley signed my jersey at a game and it looked terrible. I used rubbing alcohol and fingenail polish remover and 4 washings to remove it. You could faintly see where it use to be, but, yea it worked.
