Well, the title says: how do you clean a ground glass without damaging it ? I have one with some fingerprints, another one with some stains, etc .. (I just got some from the Surplus Shed, cheap and ok, but a bit dirty).
Thanks,
Stefan.

You can clean it in the sink with dish soap and a sponge. Wear gloves. Rinse and drip off and then dry in a bath towel.

Regular household window cleaner works fine. If you have a ground glass where someone drew grid lines with a pencil you may have to redo them eventually. Just use a pencil.
If you have a fresnel lens made from plastic or wax then don't.
Warm water and washing up liquid, followed by glass cleaner, I use a UK product used in the glaas industry "Nilglas" but it's very similar to screen was used for cars.

As others have already said, dish soap and hot water. Perhaps some windex....clean it just as you would clean glass.
If it's not too dirty I just use a microfibre cloth and maybe some lens cleaning fluid or windex.

Give yourself a gift of Invisible Glass (http://www.invisibleglass.com/), the best window cleaner made. I don't know what is in it, but it cleans without leaving any smears or haze.
Use a new microfiber cloth.
But don't wash a Deardorff GG.

I am vaguely aware that some GG/Fresnel assemblies are joined with a wax . . .what cleaning technique is advisable in this case?
