Removing Patio Rust Stains
LESLIE: Doug in Florida is on the line with a question about a patio. What’s going on at your money pit?
DOUG: I’ve got a concrete deck around a large – or deck area around my pool. And when it rains, wherever I’ve got patio furniture, it creates rust stains. And also, where the ladders and the handrails come out of the pool, there’s always rust stains around that.
And I use a product from Home Depot called Goof Off that works great temporarily. It goes away immediately but then it always seems to come back with time – in a couple weeks’ time. I’m wondering if there’s a permanent solution to get rid of those rust stains.
TOM: So this is from rain? It’s not from the sprinklers?
DOUG: Well, it’s a combination. I’ve got it close to the pool where the sprinklers don’t hit and then I’ve got it on the edges from the sprinklers, also.
TOM: It’s pretty common when it happens because of the sprinklers and the only way to deal with that is to put some sort of a water-filtration system on it that’s going to keep that iron out of the water. So it’s basically iron in the groundwater that is causing that rust deposit. And so it’s no surprise that it’s coming back in two weeks, because it just continues to re-accumulate.
In terms of the rust that occurs around the furniture or around the pool ladder, I’m thinking that that’s probably because water is collecting there, just draining down and kind of sitting in that area. That’s why it looks more obvious, Doug. Because I don’t think it’s rust that’s actually forming in the furniture or the pool ladder, because those would not be metals that are going to rust.
So I think this is mostly what is actually in that groundwater that’s landing on that surface and causing this rust-stain deposit to happen. And you’re right, Goof Off does work really super well for that.
DOUG: And there’s no real permanent solution then for it, huh? Just keep using that.
TOM: Yeah, exactly. I mean you can’t stop Mother Nature unless – with the sprinkler system, like I said, if you were to put an iron-based filter in it, that would stop the iron deposits from getting through the water and onto the patio surface. So that would have a big impact on it. But of course, there’s an expense associated with that.
DOUG: Right. Is that a filter that goes on the pump that comes from the well or …?
TOM: Yes, exactly.
DOUG: OK. OK.
TOM: Yep. Yep. Between the well and the heads, basically. Mm-hmm.
DOUG: Should I – is that something I can do myself or …?
TOM: You know, it’s not terribly difficult if you are pretty handy with plumbing projects.
DOUG: Yeah, not so much, so …
TOM: You might want to have your sprinkler pro do that.
LESLIE: At least he’s honest. Doug’s honest.
DOUG: Gotcha. Well, great, guys. Thanks for your – thanks for answering my question.
TOM: Alright? Alright. Yeah. Good luck with that. You’re on the right track. Thanks so much for calling us at 888-MONEY-PIT.
