      I have no experience cleaning brass and I now think that there’s probably a laquer coating.  It’s a blotchy brown colour that looks pretty bad.  After watching some Youtube videos recommending a paste composed of vinegar, salt and flour I gave it a try on the underside for 1.5 hours and it turned some of the brass pink!  Vigorous scrubbing with Brasso seems to get rid of most of this though.
       
      I later tried the paste for about 15 minutes on a small portion and it seemed to take off the brown stuff completely and with a following scrub with Brasso it doesn’t look too bad and it didn’t turn pink.  So far, this paste has worked better than any other method and I’ll try to do some more of the tank and see how it goes.
       
      Brasso smells like it’s mostly ammonia and seems to work well on lightly tarnished areas.  I saw a video where someone recommend using Zippo lighter fluid after Brasso to give it a mirror shine.  Any thoughts on this?  My hardware store sells lighter fluid in the metal cleaning/polishing section.  I had wondered why this was.

      Here.s a link to some chemicals from EPI:

      They sell samples.  Have you tried ammonia after removing laquer?

      I, too was wondering if there's some sort of sealer on the brass that's keeping you from cleaning it. Perhaps testing with laquer thinner and a toothbrush to see if it makes following up with polish possible.

      For brass, before polishing, it's often wise to dip in some sort of cleaner. I'm not sure what that cleaner is, but I've seen it completely brighten brass in a minute or so. I'll try to figure out what that chemical is, but I think its some dilution of phosphoric acid.

      Brian,

      Is is possible you have lacquer sealing the brass. That will get gummy and not want to come off but keeps the brass dark.. I would fear the wire brush would be too coarse to use on the finish?

      I’ve got a brass fount for a Valor Junior #56 that I’m trying to clean but it’s very heavily tarnished.  A steel brush on my Dremel didn’t work, and Brasso got some of it off but most of it won’t budge.  Does anyone have any suggestions for cleaning this without discolouring or damaging the brass somehow?
       
      Thanks.
