I must confess that I did not follow [USER=100731]@Roerbakmix[/USER]'s excellent advice to a T (sorry), since I did begin with some careful mechanical cleaning. The deposits on Apollo's hair came off with a bamboo skewer almost no effort applied, revealing the surfaces you'll see below underneath. </p><p><br /></p><p>After a brief soak in distilled water (there was a powdery residue beneath the adhesions), a level of detail I consider equal to the rest of the obverse was found preserved on the hair underneath, so I consider it a success. The question now becomes whether I should leave well enough alone, or whether I should use sodium thiosulphate to try and remove some of the other additional deposits which leave the obverse looking rough. </p><p><br /></p><p>[ATTACH=full]1008841[/ATTACH][/QUOTE]</p><p><br /></p>
