What to do when plastic becomes sticky?

Discussion in 'Electronic Equipment' started by Fred McKenzie, Dec 4, 2009.

  1. Over the years, I've had several pieces of equipment with plastic parts
    that have become sticky. The latest is the rubberized part of a Sears
    Craftsman High Temperature Infrared Thermometer. There is also the
    rubberized case of a Radio Shack HTX-200 Two Meter Handheld radio.

    Does anyone know of a treatment for these sticky surfaces?

    Know? No, but a couple of ideas. A clear acrylic coating might work.
    Mask off the unaffected areas and airbrush on a light coat or two of
    Future acrylic. http://www.swannysmodels.com/TheCompleteFuture.html

    Or, just try rubbing the sticky sections with talc?

    Try vinegar. Let us know if it worked.

    Robert-

    That is what I was thinking. I was hoping there was some chemical that
    would "passivate" the decomposing plastic.

    I have some 100% Isopropyl Alcohol (fuel line water remover) that I'll
    try, just in case that works. If it does, I expect it will just be a
    matter of time before the remaining plastic starts to decompose.

    Robb-

    I liked the idea of using alcohol because it would probably not hurt the
    underlying plastic. I tried some Isopropyl Alcohol (fuel line water
    remover) on the Infrared Thermometer. Just as you said, it wiped away
    the sticky coating.

    I was surprised that the "rubberized" surface was actually a coating
    that had been painted onto the plastic. The alcohol acted as a paint
    remover. If I can disassemble the Two Meter Handheld radio's case, I'll
    give it a try as well. It is just too intricate to clean without
    getting sticky stuff inside the radio.

    Thanks for posting. I have a hairdryer whose plastic-covered handle was sticky. I tried soap, oil, and Goo-Gone. Nothing worked until I found this thread. I cleaned it with 70% isopropyl rubbing alcohol (because that's what I had) and no more sticky handle. I then applied the same treatment to the electric cord of my Kitchen Aide mixer that I thought for years was persistently gathering kitchen grease. No more sticky cord!
