I let the grout dry the 24hrs and went back to clean the haze. I notice the tiles are covered with little tiny bumps that feel like sand particles. How can I remove them as the regular sponge cleaning isn't doing it so far. Should I go with the citrus cleaner and hot water or will they wear off with time.

Thanks
