    You can temporarily get rid of the stickiness by wiping with a cloth
    soaked in isopropyl alcohol, although the stickiness will reappear in
    time. The simplest and cheapest way is to use talc (now corn starch)
    rubbed all over it. Once again, though, the stickiness will eventually
    bleed through.

    There's a plethora of cures on the 'net. Which work depend on the plastics and plasticisers...

    I can think of three off the bat:
    -- cover it up (cornstarch, talc, a wrap of something)
    -- soak it off (white spirit, orange terpenes, IPA, ...)
    -- scrape it off (knife, card scraper, steel wool, pot cleaner, old credit card...)

    Mix and combine them, too... so soak in white spirit, scrape off, etc.

    It's mainly certain kinds of plastic that this happens to; something to
    do with the plasticiser.

    I don't think there's a remedy.

    Well, I will give a few of them a try.

    Thanks everyone.

    I've had it happen with some types of computer keyboard which had a matt black, anti-slip finish on the border around the QWERTY keyboard layout.
    It goes sticky and horrible. IPA or something similar can help for a
    while, but it's not permanent. I think on one keyboard, the IPA softened
    the sticky coating enough that it could be scraped off; then it *was* a permanent fix.
    Well all the greens were screaming for biodegradable plastics and now
    complain when they find one...

    Make a paste with bicarb and a little water. Rub this in fairly
    forcefully with your fingers and then wipe it off. You may have to do it twice.

    This works. IPA also works but takes _much_ more effort.

    those red rubber bungs used on demijohns eventually go a bit sticky, but
    ...(and this is just a theory) its possible that the process is slowed
    or stopped by prolonged contact with alcohol

    There was a thread here about this some time ago. The conclusion was to
    use isopropyl alcohol although it needs a LOT of rubbing. Some say to
    apply a protective coat afterwards, such as WD-40, but I'm not so sure
    this helps.

    another theory (not mine) is that its in some way connected to the
    amount of sulphur in, and added to wine
