Gents:
Jazzbass told me to get an ultrasonic cleaner. Couldn't find one anywhere. So my wife ordered me a Sharpertek Heated Ultrasonic Cleaner.
My Champion and white gold wedding band were the guinnea pigs. Used hot tap water and Dawn (per Jazzbass instructions). Didn't use the heater. Turned it on for 5 mintues to "get the gas out of the solution".
Then, cleaned the items for 5 minutes. NICE!!
Mother in law then stated: "Clean my jewelry!!" So did the wife.
5 mintues later, the bling was back.
Can't wait to try it on my other knives back home.
