    I bought a 1 pound tub of flux about 6 months ago. It's been about a month since I've needed to use it. I went to do so, yesterday and noticed a green speck of mold on the inside of the lid. Looking in the tub, there are tons of white mold spots all through it. Is this normal? I keep it in my climate controlled home, so it isn't getting extreme temp changes. Now I gotta buy new stuff.

    What do you use flux for?

    Any soldering I've done is all flux core.

    #3 10 months ago

    Haven't used flux in like 15 years

    #4 10 months ago

    I wouldn't think so. What brand is it?

    Personally, I've always used rosin core solder. No having to mess with flux separately.

    #5 10 months ago

    I’ve got plenty of tubs of flux that are ancient. I mean 30+ years old and they’re fine. No mold.
    I didn’t even know mold could possibly be supported in flux?!

    It's weird. I can post pics tomorrow. I find that flux helps alot when replacing sockets. Especially trying to get old solder and new solder to mix if needing to reflow a coil lug or something.

    It can def help with that — althoughfor lugs and dockets id recommend getting a cheap solder gun. Life changer for me.. makes quick work of those kinds or repairs and little need for flux

    by old and new solder, I hope that by new, you are still using 60/40 lead based otherwise that is probably your issue. lead-free and leaded solder do not mix well due to their chemical make-up and different melting temperatures

    Wow I'm really surprised at all who do not use flux other than what comes with core solders. I've always used flux as it absolutely helps with reflows and any soldering in general.

    #10 10 months ago

    I never use flux for wire soldering.
    Definately use it for plumbing pipe solder work.
    I have had it hang around for years and not have mold. It is an acid so that must be some resiliant mold.
    Mutant mold

    It depends what you're doing. If you're repopulating a board, you're going to use plenty of flux, but rosin core is fine for everything else. I spent a summer working in a circuit board factory when i was 19. I'm still using the same spool of rosin core solder that left with me 24 years later for board work.

    I do all my board work Rosin core no issues.

    I'd love to see a pic, and also confirmation of what solder you are using per j_m_'s question.

    I wonder if there's some contaminant that has gotten into it. You haven't been eating toast while soldering, right?

    Or sticking something else in it either @treborlicec ? Just kidding.. Kester 44 60/40 solder ftw. Rarely use a sep flux for board work. I think the type of solder (lead-free/vs leaded) def makes a difference. Quality of solder goes a long way.

    It was great seeing you at LAX last weekend!

    Well... rosin core flux is pretty much pine tree sap with additives. Sticky and I imagine it could support mold growth. But I have never seen flux mold before. We have bottles of flux that are years old with no mold. They do dry out over a long period, though.
    Typically add flux during rework - makes reflow easier. Used to use flux to remove SMT components but now use ChipQuick.
    And splurge a bit - go to 63/37 solder. That small difference in ratio between 63/37 and 60/40 makes a big difference in reducing bad solder joints.

    Argh! Totally agree and what I have been using for board work!

    I never use lead free. Here's pics. Great seeing you too, Jeremy.

    I just use liquid rosin flux. I've had the same bottle for 20 years and still gets the job done when I need it.

    My previous tub was like this.

    More amber jelly looking rather than creamy vaseline looking.

    I knew it! You do use flux on your uh...logic probe?

    Makes it easier to probe stuff. Duh!

    I don’t use it but the waxy flux always gets moldy. Still works but I hardly ever need to use it. Only when some crappy plated wire won’t take solder.

    My older radioshack jelly type never had an issue. I'll order some more of that style next.

    Never seen this before, although I usually use liquid flux (either in a pen or bottle with brush-on applicator). Any particular reason you're using the thicker stuff? For my money, the pen has gotten the most usage between home projects and reworks/debug at my actual job.
