Weird corrosion around entry lock (2001 Boxster S)

Hey all,

need to crowdsource some wisdom. Just in the last couple of weeks I've seen some corrosion around
the lock. This is making me nervous - wondering if this is normal and an application of Simple Green or WD40 is called for to clean it up?

Looks suspiciously like the corrosion I might get on battery terminals. Could there be a short in my door? (No signs of it other than the electronic
keys no longer work - but that could be them..).

Advice welcome.

thanks,
Stefan

ps. btw, do I really have to post an image link to a third-party site to get a picture on this site? That seems so 1995..

keeps the storage expense down and the bandwidth expense down. Always remember someone else is paying.
