 It's white, and I'm trying to figure out how to take it off. Do you think it's the result of a leak, Tom? Yeah, moisture building up. It's not just in one spot. It's all along the whole bottom strut on the whole porch. So if it's a mineral deposit, the easiest way to get rid of that is with a white vinegar and water solution because the vinegar will melt the salts. Okay.
