I lent my Rift + Touch to a friend for a while and when it came back there was something sticky on the left control (sugary drink?). I cleaned it off but I suspect some of it had gotten into the 'Y' button. It still works, but it comes back up slowly when I release it. It feels "sticky" on the way down and up.
Is there an easy way to clean it without taking the control apart? A drop of something (alcohol? bicycle oil?) and then just exercise it a bit?
If I have to take it apart, will it help? Can I access and clean the button easily? At this time I don't want to do anything too risky as it still works.
