One if the from realities of making the jewelry for which my family is known is that once it is polished it has to be cleaned. I polished for my Dad for many years and we used hit water, the basic toothbrush, and Dawn detergent to get the polish out of the twists in the bracelets. The hot water would soften the bristles and they did an ok job of cleaning out the gunk.
Recently, because of some hand injuries, I started using a paint brush, 2" sash tool,. And it does a better job. The bristles get into the depths of the cuff bracelets very nicely. And it only took about 40 years to learn this trick.
My next try may be a commercial glass and bottle washer brush.
