How do carb restorers clean the outside of the carb?

What is an ultrasonic cleaner??
Thanks for the info. Ultrasonics are very expensive cleaners like the jewlry store uses to clean your wifes wedding ring. LOL[/QUOTE]

No wife!! No ring......YET!! Hey you know what mike, what about jewellery cleaner?? No idea how xpensive it is, but I bet it would work awesome. I just googled liquid jewellery cleaner and sears has it for $7.50 for 236 ml. Pretty pricey, but I bet its cheaper elsewhere.
