I have a pair of antique globs in my head that have trued black when light is off from a bad water heater. Color comes through when light is on. Anyone know what I can use to clean them. Had an old timer tell me to get some battery acid and soak them. I have tried several paint and varnish removers, nothing is working. The brass polished right up from being black. The wife has let me know if I had fixed the water heater the globs 0would be ok still.

Yes, hydrogen peroxide might work, but I'm afraid the 3% stuff from a drugstore might be too weak. But it is worth a try - has to be a good soaking, and you need to remove all traces of solvent from it first.

You mean antique globes on your light fixtures try a paste mixed from vinegar and flour let it sit until dry then wash off with plenty of water it takes patina off things quite well and just an FYI hydrogen sulfide is a deadly sewer gas

If you know someone who wears dentures ..... Lay the globes horizontally into a ceramic bowl filled to the top of and covering the globes with water, then put four to six 'denture tablets' into the waters, let soak for several days; the 'fizzing' action from the denture tablets should clean off the micro-soot that's penetrated into the surface of the glass.

I have had good luck cleaning antique glass with borax, very gentle, I would try soaking it in a solution of 20 mule team and water first as it is quite gentile. I would not use battery acid that will likely destroy them. Even vinegar may etch them if left on too long. I believe sulfuric acid (battery acid) is used for etching glass.

Most importantly how was this caused by a water heater? If you have an unvented propane water heater just pitch it not worth fixing as it will kill you. What kind of boat is it? Seems a lot of the Canadian boats used the propane heaters even though on most of them it says "not for installation on a boat." Never could figure out how having an unvented flame in a water heater was acceptable. They do provide nice hot water when on the hook, but could well kill you with a nice warm shower to send you out.
