I will occasionally take a moist towel and wipe them off, but I've never swept them.
Seriously... the disconnect between swinging them as I would an iron, versus a fairway wood, would only become more of a conundrum for me years later. The hybrid kinda looks like a fairway wood, thus the disconnect for me. It progressively got worse, I'm guessing because I would try to find a happy medium somewhere in between.
In other words, my mind became so cluttered with proper setup (iron or fairway wood???) that I was pretty much fubarred long before it came time to swing the club because of all the mental masturbation.
I eventually ended up going back to the trusty old 5wood and 7wood.
