Mike, mowing it is what I was thinking about also but using an old electric razor or trimmer and vacuuming as Maxman suggested.

Just a quick belated update. I used my beard trimmer on the static grass and it worked! No damage done to the trimmer that I have noticed.
Glad to hear that you got some good results, as I was about to suggest that sandpaper would likely do a pretty good job of cleaning-up the mess.
Cheers,
Wayne
