Rode my bike to work yesterday and 10 minutes before I leave to go home a pop up thunderstorm occurs. I waited the heavy down pour out and then rode the mile home in light rain. Pulled into the garage shut the bike off and went about the rest of my day. This morning I rode to work and pulled the key out that I left in over night and noticed the shiny key now has a couple spots that look like galvanic corrosion. Hind sight, I shouldn't have left my key in the ignition over night because it was wet, however we are past that. I know guys that work on locks for doors in buildings say to never put wd40 in a lock as it will attract dirt and cause issues, they always use graphite. I'm curious if anyone has any suggestions as if this is a good idea or bad idea. I would think I need to drive the moisture out of the ignition but maybe sitting outside in the 90*+ heat today will do that.
