How do you repair sickness in sterling silver

I have purchased several pieces of sterling silver with small scattered black dots on the surface. I understand these black spots are called "sickness".

How is the best way to remove this sickness from sterling silver?
When I tried polishing by hand it not only took forever but I had mixed results. Should I use a Dremel [on eBay or Amazon] tool and buff the various spots out?

Any help would be appreciated.

Thank you for your time.

I haven't heard that term "sickness" myself, but try to clean silver by contact with aluminum in a solution of washing soda [on eBay or Amazon] as described in several letters here, including letter 4785.
