I was just reading a thread about a guy that resealed his aquarium, and had a real hard time cleaning up the silicone. Windex works great, i'm a commercial plumber and when ever I silicone anything I use windex to mak it a nice clean seam (an old industry trick). It will clean silicone off of any smooth surface as good as water cleans up latex painters caulk. Anyway hope this helps someone.
