They are probably bronze. Your options are:
1. Leave them to acquire the much-prized patina that you only get with bronze.
2. Polish them with an abrasive like Brasso at least once a week plus Bank Holidays.
3. Gold plate them like some of the Americas Cup boats.
4. Varnish or lacquer them after polishing first. Every year the varnish will partially peel off, giving you the opportunity to spend several days cleaning them back to bare metal and choosing one of the alternatives from this list.

Bronze..
1...Dunk in jewlers safety pickle..... scouring pad and toothbrush the crud off. (gloves, fireproof overalls, 2 ambulances in attendance, Signed proof of prior reading of EU directive Blah, Blah... /forums/images/graemlins/mad.gif )
2....Polish with chrome polish untill really really very really bored.
3....Fit to boat. Wash porthole occasionally. Dont let crud build up.. especially guano.
Do NOT polish.. ever ever again.
10 years time you will have the perfect patina
P.S. Dont forget to give your Mother in law her toothbrush back . /forums/images/graemlins/laugh.gif

Bond the portholes to a left hand anode using 5 sq mm braided wire, anodise the anodes to the mast with zinc chromate paste and ensure the triatic stay is well boused down. If that fails, fall back on Victorious's option 1.

I prefer srp01983 option 1 personally - once you start polishing you just can't stop (hey I should have been in advertising /forums/images/graemlins/smile.gif )

I believe that the IALA, and the Confederation of Commissioned Naval Officers, as well as the Ordinary Members of the Gentlemen's Luxury-Yacht-Owners Club choose Underlings' Elbow Grease as the preferred method!

Cleaning brozne: try some cheap brown sauce. No, really, it works. Not as well as Coke, but that is hard to keep on the porthole surround. Try leaving a grubby old penny in a glass of Coke overnight and you drink that stuff! Now try in soe own brand brown sauce.
See. Its an old modeller's and jeweller's trick for finicky and fiddly things that need to be soldering clean.
