How to Clean Mineral Deposits from Excess Moisture
TOM (CALLER): I have a three-season porch, aluminum. And the inside, on the struts – not the panels themselves but the support struts that support them – I have like an oxidation or mineral deposit. And it’s white and I’m trying to figure out how to take it off.
TOM: Do you think it’s the result of a leak, Tom?
TOM (CALLER): Yeah, moisture building up. It’s not just in one spot. It’s all along the whole bottom strut, on the whole porch.
TOM: So if it’s a mineral deposit, the easiest way to get rid of that is with a vinegar – a white-vinegar-and-water solution. Because the vinegar will melt the salts.
TOM (CALLER): OK.
TOM: Now, if that takes it off, great. It’s not going to stop it from reappearing. If that’s the condition, what you really need to do is look for ways to dehumidify that space. Because the moisture is going to continue to condense on that and form those deposits, even if you were to get it clean again.
The other product that you could think about using is called CLR – Calcium, Lime, Rust Remover. That’s another type of mineral-salt cleaner that’s a little bit stronger than vinegar and water but that will also work, as well.
TOM (CALLER): OK. That won’t take the – it’s anodized aluminum. It’s that brown, bronzed aluminum for a three-season porch. That won’t affect it? The CLR?
TOM: I don’t believe it will. But you could always try it in a – you know, they always say test a small area. But I think you’re going to find that the reaction of that material on the salts will just melt it away.
TOM (CALLER): OK. I’ll give that a try.
TOM: Alright. Well, good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
