You need a commercial type soap and scum remover,and maybe even a steamcleaner or high pressure extractor machine. But first try a soap and scum remover from HD or Lowes,or online, and your grout brush,then if that helps a cleaning with some sulfamic acid crystals and the grout brush oughta bring back the original color, then rinse,let dry, and seal.
