I would clean out the airlock and replace it with new water or vodka. Poeple ferment wine in open fermenters so I am sure you are fine. I notice even with starsan after a couple months the water starts to get icky. For long term fermenting 3 months and longer you should probably use the hard liquor method. just so you don't have to clean it or worry.
I always use cheap vodka in my airlocks. The airlock looks fine, though I think I may have let the level drop in the summer at one point.
