Hi Poppy, Is your ultrasonic heated at the time? If so, try it cold
and see if the same thing results. I’ve heard people say (rumors) that
sterling shouldn’t be in a heated ultrasonic, but I’ve never been
able to pin anyone down on it.
I’ve been using the solution that comes with the Speed-Brite “bolt
on” ionic cleaner. I use it hot and have never noticed an issue with
sterling. Then again, I guess the ionic action could be eliminating
the tarnish as it forms.
I would be quite interested to know if the temperature has any
bearing… please report back to us?
P.S. Nothing on the tarnish prevention strips…
All the best,
