Posto oggi qualcosa che va al di fuori del mio seminato, ossia parte di un distintivo dell'ODVF (Общество друзей воздушного флота, Società degli Amici dell'Aviazione). Come riportato qui, la Società fu fondata nel 1923 e includeva tra i suoi membri, figure di primo piano come Dzerzinsky, Frunze, Antonov-Ovseenko e Lunacharsky.

Ho preso questa stella per 9$ insieme con una stella da pilotka da scavo senza pensarci nemmeno un secondo e avendo in mente le meravigliose stella dell'OSOAVIAKhIM (mostrate qui e qui).

Sfortunatamente non di fregio si tratta, ma di parte di un rarissimo distintivo, che vado quindi a mostrare nella sua interezza. Mi ha insospettito da quasi subito quanto rimane delle due stanghette di fissaggio sui raggi della stella e l'assenza del tipico punto di fissaggio centrale delle stanghette dei fregi Sovietici.
Tutto sommato non m'è andata male comunque e ad ogni modo terrò gelosamente questa stella tra i miei fregi.

Domanda però, come pulirla
Le ho dato una passata con cotton fioc e acqua calda. Vado di alcol?

Wow! Will you try to remove the dirt? (I'm thinking of an olive oil smooth bath)

Dear Komsomol..sorry, I forgot to provide english translation of my post..

As a matter of fact, I was indeed asking you all gents some suggestions on how to clean this little jewel here. You would suggest an olive oil smooth bath? And..how would that actually work (I am terribly ignorant when it comes to procedures for cleaning dug-up pieces).

Thanks!

Well, this technique of the olive oil bath requires a LOT of patience. It has been suggested by an evil numistatics collector - our dear Lapa .
I succeeded to remove some "vert-de-gris" rust on some badges. About the red ferrous oxydation, I am unsure.

GC,

On the front side, it looks like dirt. I would soak it in distillated water for some time (at least a week) and then gently try to dislodge the dirt gently using a wooden toothpick. If that doesn't work, then go to further more radical methods.

It indeed is, I was able to remove most dirt from the propeller with a cotton bud simply dip into warm water. I did not however venture in any radical operation over the dirt stuck around the CCCP letters, because I feared I could damage what could be left of the enamel under it.

I'll proceed with the distilled water and in one week we'll hopefully be looking to more red colour!

Thanks for your advice!

The result of the distilled water bath and toothpick removal process is quite impressive. The enamel under the rather thick strata of dirt that used to cover much of the star is entirely intact

Any suggestions about how I should proceed now gents?

Thanks again!

Visto che lo smalto è intatto, io penso che a questo punto puoi usare l'olio d'oliva, farlo agire per qualche tempo per far si che si ammorbidisca lo sporco, e poi usare un cotton sullo smalto, e uno stecchino da denti sulle parti solo metalliche.

GC,

Since it's working, I'd keep soaking the star in water and gently scrubbing it with a wooden toothpick. I'd keep the olive oil as a last resort since it is somewhat acidic and will react with whatever copper is contained in the metal, permanently discolorating it in the process.

Marc

Thank you all! I'll give it another good week of distilled water and then we'll see if there's need for some good quality Italian extra-virgin olive oil

Grazie a tutti! Gli darò un'altra settimana di acqua distillata e poi vedremo se ci sarà bisogno di un po' di ottimo olio extra-vergine italiano!

Bel colpo Gió

Per curiosità la distillata la usi perchè leggermente acida?

Non ne ho la bencheminima idea , chiedi agli esperti!

Comunque, risultato di un'altra settimana di immersione in acqua distillata. Le tracce di terra e lo sporto sono stati praticamente rimossi del tutto. Ora mi trovo di fronte al pericolo e alle tracce dell'ossidazione. Consigli?

Nevertheless, this is the result after a further week of immersion in distilled water. The traces of dirt have been almost entirely removed. Now though, I find myself facing the danger and traces of oxidation. Suggestions?

Grazie / Thanks / Spasibo

Nice result so far, GC

Before going any further, we need to determine the metal composition:
. is it brass/bronze?
. is it magnetic?
From your answers, we'll see in which direction to go.

Marc

Thanks Marc! I am indeed very happy with the result so far. I was hoping for the star to be so nicely undamaged, but feared that under the dirt I might find missing enamel, which was thankfully not the case..

So, the metal is definitely not magnetic, so probably brass/bronze. Any help will be, as usual, highly appreciated!

OK, that is good! Had it been copper/brass plated steel, we would potentially have had problems.

So, I would suggest a "gentler" approach to start with: immerse the star in Coca-Cola for a couple of days and then see if any of the corrosion gets loose (using our good old wooden toothpick). Then put it back in for another couple of days and repeat the procedure a couple of times and give us some feedback

Sorry for the delay guys! Curremtly on a short holiday and (thankfully!) my access to the internet is limited.

Will definitely go ahear with the coca-cola strategy, comcealing the shole thing from the organs of state security

Will come back to you in a week time and hopefully we'll see some further improvements!

There we go, this is the final result!

Several further treatments with distilled water and coca cola. After that the dirt had been removed, but in doing that, the rusty bits of the badge emerged. So I decided to delicately clean them away with a tooth brush and some lemon juice.

The photos aren't the best ones I've ever made , but they should give an idea of how different the badge now looks, in comparison with the moment I acquired it.

Thanks to everybody who joined in and helped me properly cleaning up this little beauty here!
