A clean razor blade will not scratch the glass. However, if it begins to rust it
will. Dry it after every use and check the edge every so often for rust.

A better alternative is to use "snap-off utility knife blades". These can be
found at most hardware stores. A snap-off blade is about 6" long and can be
broken into maybe 6 pieces. In use, when the end is dull, snap it off and you
have a fresh end to work with. For cleaning glass, use the whole thing. It's
much wider than a razor blade!
I use these with a wooden holder. Get a piece of wood molding, 1/2" x 1/2", and
make a thin, deep groove in one face and insert the whole snap-off blade in the
groove. If you are clever, you can space the end of the blade in a bit from the
end of the wood - this keeps you from scraping off the silicon sealer at the
tank corners.
