Brasso?Yes - pretty much any household acid will do the job...though some are likely to be less messy than others.

Brasso?
Really? Can't be the only mode of action shurelyIt's a mechanical (abrading) means of removing verdigris though

There seems to be some chemical action too... Brasso turns from creamy to black, brass turns brassy
Cosmetic finish...meaning... patina?...that'll have implications for the cosmetic finish of the horn...

Wow that worked better than I would have expected, actually.It works because the active ingredient is a weak acid (oxalic, in this instance).
Here's how another acid (citric) works - minus the scratch-brushing. This is from an article I'm currently working on about methods to deal with verdigris.

How did you apply it and how long did you leave it on ? Did you use an abrasive tool as well (toothbrush, whatever ?) Or was it purely applying the acid and letting it sit and do its thing >
You could use T-cut, rather less abrasive than Brasso.
...or a fingernailIt would be more effective to use harsher abrasives more accurately - hence the recommendation for the fibreglass pencil
Ah ... that would explain why you didn't last long in the army.a fingernail
Tends to be my method of attack
I think Steve is talking about Brasso liquid on a cloth whereas perhaps you are thinking of Brasso wadding?Really? Can't be the only mode of action shurely

The wadding does seem to make brass shine with a wipe over but I don't know if the liquid contained in the wadding is simply Brasso liquid or some other composition? @Stephen Howard - any ideas?
Not tempted to foray into well aged urine?Ammonia is interesting stuff inasmuch as while weak solutions will lighten up a mild tarnish, stronger ones will accentuate it. It's often used in patination solutions.
