put them in bleach for a day or two.
remove all the hardware because bleach can damage aluminium parts when putting it too long in the bleach!
I did it with my skyway tuff wheels and worked nice, not perfect but...all depends on how yellowed the wheels are.
mmmm then you have a problem.
but i supose there is no magical cure to get them back in new condition.
my white tuffs were better after 2 days in bleach water, but still not as white like new.
did you try the old school BMX forums?
Yeah I guess your probaly right, its not like they are YELLOW, just not super bright white. Was thinking of testing a small spot with some super fine wet sand paper to see if that removes the top layer at all. I have not tried any other forums, just happen to spend a lot time on this site so I figured Id give it a try. Thanks for all your help!
