How do you remove grout haze from stone tile?

Question

contractor failed to seal tile "before" grout - we sealed the tile and grout haze was never removed. also grout is too light in color. how can i make the grout darker?

Answer 1

Go to home Depot or Lowes and buy what they recommend to remove the sealer and then wash the tile with vinegar. Vinegar will remove the haze.  Get a grout colorizer frome Home Depot / Lowes and carefully dye the grout and then reseal.
