Hello everyone!

I impulsively bought my first walnut pairs a week and a half ago so I didn't really know much. I ended up getting an already polished pair with an uneven shine between the surfaces and the crevices. I also noticed that there are areas where the crevices seemed to be dirtier with gray or black spots, and there were also areas where it was still whitish/yellowish. Do I need to brush those areas more? Would they still even out eventually?
