Yes. Rinse it.

Thank you Vladimir, I was hoping so. Whenever I prepare the reptibark, I use a mesh laundry bag when I do my overnight soaks, that way I can just pull it out of the container (I haven't drilled holes in it yet), rinse again with the hose, and let it drip dry a bit before I use it. Today, once I pulled it out, I thoroughly rinsed it (much longer than usual) and I'll let it sit until Sunday when I'm ready to use. With this 4 day soak, I may have ruined one of my bench parts. I use this heavy block to keep the laundry bag from floating when I do the soak. A one day soak is ok, but having it sit in the brown water for so long has tinted it! Gardening problems.

I've left mine sitting for much longer...it will be fine!

Thank you both. I wish garden web had a big "resolved" checkmark I could check right next to my initial post once my simple question was answered!
