The first time I used Chain-L, the chain developed surface rust before it started squeaking or shifting poorly. That was after about 1,200 miles, IIRC, including a fair number of wet rides.

The grinding sound isn't good; if there's grit in the interior of the chain, where you can hear the grinding, it'll wear the chain. If a wipe down will clear it, that's good. Otherwise, the chain must undergo cleaning, and the need for re-lube depends on how thorough the cleaning is. Wipe with a thinner on the rag? Don't worry about it. On-bike brush cleaner, or off-bike soak, and the chain needs more lube.
