One key on my thin bluetooth keyboard is sticking... I'm not sure how, but I guess something got spilled or lodged under it. Is there any non-destructive way to clean under the keys?
Take a business card and use the corners to dig around the key. Then the long edges to scrape underneath the key. Followed by a few blasts of compressed air should do the trick.
i usually just use some Lysol whipes to clean the surface and than wrap it around either a business card or spudger, to get into the small areas under the keys.
