Mulch dye stained concrete.

EPERRINGTON

So I spread all my mulch out about a week ago and the day after it started to rain and has been since. When it started to rain I began to notice black streaks (color of the mulch is black) showing up in my sidewalk and driveway that surrounds the mulch beds. Now that the rain quit I have black streaks in my concrete that appears to be stained into the concrete.

Any ideas in how to get rid of mulch dye stains in conrete?

Spring rains and the summer sun will bleach the concrete back to normal in a few months. A little vinegar poured on will speed up the process.
