Remove Moldy Shower Caulk

  • Transcript

    LESLIE: Veer in Delaware, you’ve got The Money Pit. What can we do for you today?

    VEER: I have a mold that’s built up between the shower doors, which are aluminum, to the fiberglass that the shower is made of. Right in the connection between the door and the shower and the fiberglass, there is a mold that – I see it but nothing cleans it.

    TOM: What have you tried? Have you tried bleach? Straight bleach?

    VEER: Yes, I’ve tried bleach. I tried OxiClean, I tried white vinegar, I tried – you name it.

    LESLIE: Now, are you seeing it on the caulking that’s sort of the connector between the two or is there no caulk in there and it’s just sort of built up?

    VEER: Yes, yes. It’s like on the caulking.

    TOM: Ah, OK.


    TOM: Well, then, now we know why it’s happening.

    LESLIE: Yeah, because once it sort of super-saturates the caulk that’s there, there’s really no cleaning it. The best bet is to remove the existing caulk and you can do that with a product that’s called a caulk softener. And you can get it at the home centers and you apply it and then it sort of peels right out; you just pull it right out.

    And then, with that open space there, clean very well with bleach; bleach and water. Let it dry; you know, really dry it out. And then, go ahead and recaulk the surface there; that sort of space between the shower door and the tub top. And that will do a great job of really giving you a fresh surface; you have cleaned it all out. And make sure when you buy the new caulk that you get one that has an antimicrobial additive, like Microban, so that it won’t grow mold.

    VEER: OK. Thank you.

    TOM: You’re very welcome. Thanks so much for calling us at 888-MONEY-PIT.
