Question on cleaning and partially restoring a Moroccan Nimcha

kronckew · 22nd June 2018, 09:45 AM

I just posted my newly arrived nicha with an enthusiasticly cleaned blade HERE the blade appears to have been sanded with very fine sandpaper on a flat block, and polished. The pits have their black oxide in them...

Rick, Fernando, thanks.
kronckew, it's a beauty. A pity about the aggressive sanding. I almost caught myself doing the same thing! I started a bit of sanding with 2000 grit paper then stopped myself before I did any real damage. I just got a bottle or Renaissance De- Corrosion fluid, it was expensive but so far seems to be helping. Last week, before that I tried Metal Rescue Rust Remover Bath brand, painting it liberally on the blade and guard then saran wrapping it all for 48 hours. Then I took a brash brush to it. It helped some.

These are all from June 15th

These are from tonight. The rust is somewhat gone from the guard, though there is deep black pitting.

In the previous photos the glossy stuff on the handle was oil. Unfortunately it deeply darkened the horn. Which is, itself, pretty badly de- aminated (I'll try to get a good close-up picture of the handle).

Cheers everyone, thanks !
