Ernie Posted July 3, 2014 Share Posted July 3, 2014 Hi Guys, I've got some ancient brass fittings for WW1 models. They were acid etched years ago, and have become really stained and dirty. Is there some magic way of cleaning them, and restoring them to their former glory? ernie Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted July 3, 2014 Share Posted July 3, 2014 Try cillit bang it should remove any oxidation but will leave them dull . Quote Link to comment Share on other sites More sharing options...

Tomtom39 Posted July 3, 2014 Share Posted July 3, 2014 I use good old Coke Cola! (Not tried any of the reduced sugar varieties though! ) . On some fittings I've cleaned them very quickly (having soaked them for a few mins in said solution) as oxidization takes place as soon as it hits the air and put on a coat of clear lacquer .

Steve Houghton 1 Posted July 3, 2014 Share Posted July 3, 2014 Yes I remember, (years ago) you could put a penny in some Coca Cola and the next morning it would be bright again. Quote Link to comment Share on other sites More sharing options...
John Miller 4 Posted July 3, 2014 Share Posted July 3, 2014 Try Citric acid, obtainable from any home brew counter or chemist used for allsorts of things. Make into a fairly strong solution with water drop your parts in (those to be cleaned of course) job done. Make sure you wash them with hot water when finished, that applies to all the cleaning agents mentioned above as well. Quote Link to comment Share on other sites More sharing options...
Kevin Wilson Posted July 3, 2014 Share Posted July 3, 2014 It was a lunchtime trick of mine to completely detarnish a 2p using brown sauce. Ketchup also works, but not quite as quickly. Surprisingly I didnt put anyone off brown sauce, so my plan failed miserably. I expect citric acid is the comon denominator in most of the suggestions Kevin Quote Link to comment Share on other sites More sharing options...
