Hello all - I am installing (with my landscaper) a new paver walkway and a portion of it will be bordering my new grass. Water from irrigation will hit it, even it if its just overspray, and i'm concerned that the iron will stain the pavers. I'm trying to figure out if I should get 'earth blend' color to hopefull blend in with the eventual staining...but that is definitely not our first choice. We would rather get a light charcoal/granite color, but i'm very concerned that the Iron will stain. Am I being overly concerned with this? Could I just use that concrete/stone cleaning solution a couple times/year? If its a risk, I'll just settle for the reddish/brown colors. Thanks for your help!
