I have Speed Brite machine and am very happy with the way it cleans
the tarnish off of silver jewelry; the people who own the company
also seem like very nice, very helpful people.
However, I don’t think it would do much for cookie dough and other
such stuff lodged into nooks and crevices . . . I don’t know . . .
perhaps it would loosen the material.
Great for tarnish though!
