I have never used Sprayway but will look for it now.

I like “Invisible Glass” spray better than Windex.

I have used newspapers many times on large 4x8 ft glass sliding doors, but like microfiber towels better still.

I have seen Magic Eraser do “minor miracles” on many surfaces and will try it (cautiously) on glass.

In the family we have many pieces of Steuben Glass to gently clean,
the art glass of animal figures made by Corning Glass Company,
as my grandfather was the longtime company employed Dermatologist burn specialist at the Corning NY glass furnaces from 1931 to 1971
