Thanks, the link does not show how to physically clean one key
"Wet a cotton swab with rubbing alcohol. (Use 95% or stronger isopropyl alcohol if possible.) Rub the cotton swab back and forth over the six circular magnets on the Type Cover's connector. After you're done, make sure the pins are dry and that no cotton fibers remain on the connector. Then clean the connector on your Surface."
There you go :)
