• How to stop black rubber from leaving dirt on shirt

    From micky@21:1/5 to All on Mon Oct 14 14:02:17 2024

    I have a set of earbuds on a neckband, black rubber, several years old,
    and the yoke has started to leave a lot of black rubber marks on my
    shirt collar.

    Can you suggest a treatment or coating to prevent this?

    The part that rubs off has no jacks or wires comeing out, it's a plain
    field but otoh, many things might not stick to its surface. It;s curved everywhere.


    It wasn't until the 3rd shirt I took the trouble to find the problem,
    and the first shirt has been washed and it came did come off in the
    laundry. I'm not a fancy guy but even I think it looks terrible.

    This is a combination hearing amplifier and bluetooth-from-the-cellphone
    and cost about $300 or 400 new, by Bose, and they don't make them
    anymore. They still sell some on ebay but I'm sure they are as old as
    mine are.

    Doesnt' that mean the battery on new old stock is old and weaker too? If
    the battery on this wears out, won't a replacement be already half-way
    as bad, just from age? Probably lithium. (Because I'm consiering buying
    real hearing aids but I fear they will keep falling out of my ears. The neckband kind do, but they don't reach the ground when they fall.)

    Cheaper ones don't give hifi sound, t hough they are still better than
    nothing.

    I don't know for this particular application, but I have used Minwax Wood Hardener
    to fix old plastic that had picked up a sticky feel. Wood Hardener is basically Crazy Glue dissolved in acetone. Acetone can be destructive to some plastics, so you
    need to be careful with it. I paint it on with a little paint brush and don't touch
    it until I'm certain it is dried. Test it on a small spot before committing to it.

    I won't like the appearance, but I don't have many choices. I hear well
    enough 90% of the time, but meetings, lectures, doctor's appts with some doctors, are a problem. (I found an app that records what we say and transcribes it. That helps a lot. Even when I hear everything, I can't remember it all.)

    That's a pretty good idea, that I would not have thought of. (I though
    of heat shrink but it gets too wide at each end.) I used to have a big
    box of that stuff that I used when I ran 3 controls, a wired cable
    channel selector, wired, on/off, and wired volume control to my bedroom
    tv and my workshop tv. I still have lots of it left, especially the
    small sstuff, but it would be hard to find after 40 years.

    It sounds like the original soft black "rubber" is in fact urethane
    polymer, which is now reverting back to urethane monomer.

    The monomer might be removable using Ethyl Acetate, found in some
    kinds of nail polish remover.

    That might be a good idea too.   Yours also were making your shirt
    dirty?   Not when new but a couple years later?

    This is probably the same as the sticky rubber coating problem discussed
    here many times.

    Almost certainly. Of the commonly available solvents likely to be found
    in your garage brake fluid is just about right for removing the nasty
    tacky surface gunge whilst not damaging the remaining good polymer.

    I was surprised how well it worked...

    That's one I have never seen before. I will keep it in mind for the next
    time I have that problem.

    I hadn't heard of that option before either.

    I would comment that (except for DOT5, which is a silicon oil), modern
    brake fluids are glycol based, and thus can be washed away with water.
    So if one has used brake fluid to remover urethane monomer, be aware
    that the monomer can precipitate out a milky haze that can re-deposit
    on nearby surfaces, so use a lot of water to flush it away before it
    can redeposit.

    May need to do the brake fluid trick twice.

    It's not sticky. It doesn't even seem dirty until I push down a litle
    when I rub it. I've had the sticky one, on a power-thing for recharging
    phones etc, and I finally did get rid of almost all the stickiness, and
    I actually used the ppower-pack my last day in florida to recharge an
    almost dead phone. It was good to have.
