Which is exactly what I would do (:%!grep -v '^#')...

But if your intent on doing it entirely in vi, try a macro recording in
command mode:
  q0/^s<ENTER>ddq10000 at 0
oh yes, and execute the above from the top line.  This saves a macro
into register 0 that 
- searches for your regex (/^s<ENTER>)
- erases the whole line if it is found
This macro is then executed 10000 times.  The first time it fails vim
aborts the macro playback, so you don't have to worry about removing
too many lines of your file.

Try
  :help record
for more info.

There may be a way to do it with regexp only, but I'm not familiar with
it.  HTH.
