Mineral Deposit Buildup on Concrete Walls

  • Transcript

    LESLIE: Theresa in Vermont has a question about her basement walls. What can we do for you today? 

    THERESA: We had a very wet summer and we have something growing on the walls of the basement. They’re not – the walls aren’t wet but there’s something growing; it looks like frost.
    LESLIE: Oh, it’s like a – sort of like a white haze, if you will?
    TOM: Like crusty stuff?
    THERESA: Yes.
    TOM: Yep.
    THERESA: It’s not hard.
    TOM: Mm-hmm. No.
    LESLIE: Mm-hmm. Well …
    THERESA: But it’s just white.
    LESLIE: Theresa, I mean you said it yourself; you had a very wet summer. So, obviously, the ground had been saturated quite a bit and even if your basement is dry, those concrete walls tend to suck in a lot of moisture from the earth; so now, what you’re seeing is when the moisture gets into the concrete and then evaporates out, it leaves behind sort of a mineral deposit and that’s that whitest haze that you’re seeing on there. It’s easily fixable. All you need to do is clean it with white vinegar and water and then make sure you rinse it kind of well with water on top of it and then, you know, dry out your basement with a dehumidifier and that white haze will go away.
    THERESA: OK. Alright. Thank you very much.
    TOM: You’re very welcome. Thanks so much for calling us at 1-888-MONEY-PIT.
