I have a Chicony 5181 with White Alps that I lubed recently. I remember it was working correctly before the cleaning that I did a few weeks ago. After I lubed the switches with a Teflon dry-lube, some of the switches stopped working or didn't work correctly. The left shift would only work for a half of the keys, the apostrpohe key stopped working completely, and other keys wouldn't register consistently.
I wonder if lubing the switches was what caused the switch failure. Using a Q-tip, I naively put lube on both sides of the slider, the click leaf, and the part of the switchplate that touches the slider. Thinking about it a bit more, it could have been the way I applied lube on the switches. If it's the lube, can I fix my switches with an ultrasonic clean?
