Help! Please don't laugh!

I would be very grateful for your help. I apologize at the outset for this being a non-Glock question. Yesterday, I was cleaning my german made 80's vintage P226 after shooting it for the first time (it was NIB). I noticed a ring of powder residue in the breech face/striker area which would not clear when scrubbed with an old tooth brush and Hoppe's solvent. Then I had the bright idea of using a bronze brush; The residue did not clean (it cleaned afterwards, when I used a copper brush), and the breech face area was stained a gold color, which I cannot now get rid off!!! Could anyone please help me to get rid of this golden color??? What do I need to do besides learning the lesson??? Thanks for your help!!

Spray a little nitro solvent on and brush with a nylon brush. It should come off.

Be sure you leave the firing pin channel dry when you're done. You don't want solvent or oil in there.

Thanks for the suggestion! Best regards.
