Clean Nickel Silver

<< < (3/3)

Enthalpy:
My mistake: the outer face of my flute has a silver layer. So cleaning with aluminium foil and bicarbonate is just the usual operation. Below the silver, the body is grey, much darker than silver hence it shouldn't be the usual nickel silver, while at the bore and the tenons it's more yellow, less so than the usual brass, and there the reaction didn't clean the metal. A workshop complained the alloy is very soft.

Aluminium and bicarbonate didn't act at the keyworks, where I suspect a strong biofilm, nor against residues from adhesive tape. 7000 grit sandpaper worked there but it removed the silver layer much faster than expected. Metal tools scratched the parts. Bone had the right hardness, I shaped a scraper of it, but access in the corners was imperfect and lengthy. The best means, especially on keyworks, were toothpaste and a toothbrush. This can replace all other means I tried.
