S2KI Honda S2000 Forums - Bride Seat Cleaner

I was hoping someone on here could send me in the right direction.I've had my Bride Exas3 seats for 3years now.i take very good care of them.I wash them w/Tuff Stuff cleaner about every other interior cleaning.its works great on the carpet & actully makes the seats look a brighter black color each time i do it.it also makes them feel soft again for a little while till their dirty again.it also helps that u can get it at the local store.but over time the Bride lettering behind ur head on the seats has been getting dirtier.turning a dirty brown color not all shiney white like all the new brides u see in peoples rides in their online buildups & articles.the question?does anyone know a good cleaner to use to bring them back to a whiter shade & something i can use to keep them as close to staying that white color.thanks ahead of time.
