I have some cheap electrical pushbutton switches that are showing signs of wear on the plastic moving part. Also, plastic "dust" is fouling the contacts. Would heavy lithium grease, mainly because I have lots of it already, be a good candidate here after cleaning?
Also read this while Googling;
"I think this is an area of rapidly diminishing returns. The difference between a good lubricant, a better lubricant, and the best lubricant is trivial compared to the differences between lubricated and unlubricated"
