No results on the pearl upper for my 1997 Pearl Foamposite left shoe. I checked this morning, the upper is still yellowed, it hasn't restored back to pearl after using Bar Keepers Friend. Can anyone please clarify if it will take multiple applications of BKF or will I have to use a different chemical to restore the pearl uppers?
