I think I may respectfully (very respectfully!) disagree. Water may not be dark, but I think that granite saturated with water may well be.

The stain in the photograph is MUCH lighter than it started out to be. I had another stain caused by leaving a wet pot lid on the counter top. The stain was a thin ring where the lid sat on the granite. Over a period of weeks this stain disappeared entirely, leaving not the faintest trace as the water dried out.

So, I have hopes for my dish detergent bottle stain, it seems to be getting better on its own, but the flour and hydrogen peroxide trick is there as a backup.
