I have only tried two of the methods grampar7 listed, sanding and bleach. Sanding definetly worked the best, but as he said, it can be quite a workout(note: if you want to alter your fingerprints - sand a couple tuff wheels with 220 grit.) I have also tried Wesley Bleach White on some real dirty white Tuff's. This worked OK, but they didnt come out as clean as I wanted. Maybe more bleach and scrubing would work - it's too cold for me to try right now!(Thursday we will have a high of -1 degrees).
