The stuff to use is good ole "Bon Ami"- which advertises that it hasn't
scratched yet!
It is recommended by Corning for cleaning glass, and their glass based
products- it is softer than the glass, and I have used it to remove crud
from many lens elements, lab ware, microscope slides, and even use it to cut
the wax and film build up on my auto windows-- Bon Ami, a rinse, and wiped
down with newspaper makes the glass sparkle- and it hasn't scratched yet!
Not as sweet smelling as toothpaste, but it is reliable!
