As you know, we have been trying to figure out how to get a healthy lawn. Yesterday, B treated it with iron oxide stuff (I don't know the specific name), and it left rust stains on our cement. All over the place! Sidewalks, driveway, back porch.
A guy at Home Depot told B that it's organic and wouldn't do that. He either lied or is ignorant.
So, how do we get it off?
I tried scrubbing it with Coke after reading that it can help with rust. Nothing. But then I had no instructions on how to do it.
We got some CLR from Home Depot (free since they screwed up), and it did NOTHING.
Help!!! I've read that the longer it's there, the harder it is to get rid of.
