I was thinking a heated ultrasonic cleaner would take care of that. But i will try after rinsing with it if a sulphuric leach will yield more hidden gold.No. The gold will be heavy flakes and will get stuck between the springy caps. It takes time to pull them apart to get all the gold out. Without the springs, you can rinse the gold out with a spray bottle.
Thanks.
