I also have seen clear and blue tinted cylinders in G&B 176’s. You should have no problem cleaning glass. Just don’t scrub so hard you scratch it. There are enough products that will work. Vinegar can get some hard stains out, but I’ve heard of people using a lot of other stuff.

PetroNuts. Com sells reproduction glass cylinders. They will also cut a cylinder down for you if it has a rough edge, but I don’t think they can guarantee it if it breaks. They are in Milford, MI.
