One thing I wanted to add. The only issue I have with Tarnx is the smell it leaves behind. This posted method, lemon or toothpaste helps with that however. Sometimes its a multi effort. With solid silver, I have even used my bench grinder with a soft wire wheel, then used steel wool, then a buffer on my Dremel. I dont need cleaner after using that method. This only works for silver bars or large silver pieces.. I have had good results on rings and large rope chains as well. I would not recommend this for thin rope chains, thin linked necklaces or similar bracelets as it may bend them or damage them. It may even break the links…

Tarnx is awesome. It is my go to. This works when it is not available however but again I fully agree with your comment.
