 Hi, Gary. Lou. Hey, we're in the process of sealing our concrete driveway. Yes, sir. And we pressure washed it, and we've got a stain. We're back in the woods, and it's an area where leaves have accumulated, and I let them lay there too long. So I wondered what you could suggest to try and get rid of that. It's a pretty nasty, ugly brown stain in the driveway.
