Removing Verdi Gris From Bone

Be careful with the Hoppes, though. I've found it to be nasty stuff. I'd flush everything out and reoil after using it.
Your right sir! My bad for failing to mention that. A solvent has the potential to dissolve brass and move it into various materials (possibly making thing worse). So a thoroughly cleaning was done after the trial with no detrimental results. (kids don't try this at home :eek:)
 
Yup, hoppes is a copper and lead solvent. Not something id be using on my knife scales or brass.

However the newer formula isn't quite as corrosive as the old stuff. I believe they removed the nitrobenzene.
 
David, I just finished trying Hoppe's solvent on small sections of some users (with Q-tip). On verdigris around a rivet in stag it was easily and completely removed. I suspect because it was on the surface only. On white bone and ivory there was no change, possibly because the verdigris was deeper (below surface stain). Will be interested to hear your and/or others results. -James-

Thanks for that. As I'd mentioned, I hadn't tried any of the suggested methods. As others have also said, it'd be a good idea to completely flush & clean the knife after the Hoppe's, due to it's affinity for the copper in brass.

I'm sure the verdigris in the OP's pictured knife has leeched into the bone. I didn't know if the Hoppe's might be able to dissolve that or otherwise remove it, if so.

I think the verdi is pretty much into the pores of the bone and looks pretty good as is.

I have used fresh lemon juice on a brass watch that I used to have and it removes light tarnish very quickly. Then rubbing in a cloth worked for stubborn spots, even with a slight mix in with baking soda works well. But lemon juice is a light acid and not sure what that would do to the bone in prolonged settings. but this natural solvent probably is the best bet. Diluting may help.
