PBT keycaps sticky after 9 months

(1/6) > >>

My Ducky doubleshot PBT keycaps are sticky and a little shiny after normal use for 9 months. I bought a second set so I've replaced them and I have the old ones in a baggie. I asked some people on Discord and they said to use a denture cleaning tablet in water for an hour. I tried that on three of the keycaps and it made no difference. Is this permanent or is there some way of making them not sticky again?

They don't feel dry. They feel sticky. Like the spacebar feels like that more where I usually hit it with my finger. I know ABS gets shiny and somewhat sticky after a few months but I've always heard PBT does not so I thought I'd be able to fix it by cleaning.

You know how if you go down a slide wearing shorts, sometimes your skin will stick to it? It can happen when you go down a waterslide on your back too..

I think a similar phenomena can be experienced with shined caps. Does that sound like what you experience in terms of stickiness?

Slusho64:
I'm not sure where the confusion is coming from. Sticky keycaps is common for ABS. I'll describe it more, though. If I rub my finger over a new keycap, it's pretty smooth (low friction). If I rub it over the older ones, the friction is higher. It's kind of gooey feeling. Like hard plastic vs soft touch/rubberized (not that much obviously).
