I bet an Xacto knife is definitely what I need. I worried that the knife's blades would snap, but its thin blades would be much better to pull up on those teeth. Here's one more little Dremel project I"m trying. I do notice that when tarnish is truly gone it polishes up perfectly, but it seems to "bake" some lingering tarnish after the polish has been driven off, and thus blackens some spots while it's polishing elsewhere. Not sure if others have run into this phenomenon, but just a bit of back and forth with the dremel and a qtip full of polish removing what the dremel didn't remove seems to be working. I will ultimately run some brass polish and a white cloth-post dremel- to finalize these buckles.
So what attachment are you using with the dremel...a polishing one, scrubbing, sanding, etc? I'm waiting on a wristlet/clutch and the hardware looks like it's going to need some help.
See, you gals are dragging me into this rehab/rescue stuff when I only want to read about all the great things you do. LOL
I use my Dremel all the time...I have five dogs and that's a lot of nails to pawdicure every week.
