Glass Cleaners - with or without Ammonia?

If you find it..

here's some directions for use on glass..
The composition of modern glass may be different now than then? So I'd test first.
And I'm guessing that the 1886 version is what you'd want. I've seen it sold at OSH

You can get Bon Ami powder on ebay. I have seen both the powder and cake forms at Orchard Supply Hardware and True Value Hardware.
