This is wha'cha need, right here.
Another collecting hobby of mine is vintage Gillette (and a few other brands) razors. I've picked up a few uncommon models in antique shops in years past, some with nastiness of the worst kind caked on, and in them. Scrubbing bubbles handles it all with no ill effects to the surfaces of the nickel-plated (or gold-plated) brass razor. Rinses readily away too. I shave with vintage razors and maintain them after each week's use by cleaning with Scrubbing Bubbles and a soft toothbrush. Surfaces have never degraded from regular use of Scrubbing Bubbles and the toothbrush.
If I acquired a grungy stainless steel bracelet I'd go for the Scrubbing Bubbles and a toothbrush.
The bottom razor is the favorite and has seen use every other week for the past six years with no deterioration.
