Toning on Silver American Eagles

About ten years ago there was a thread about guys trying different things to get some pretty toning on Silver Eagles. Enough time has gone by, did anyone have any luck?

There are a lot of posts/threads about ASEs and toning (forced or otherwise).
Taco bell napkins seem to work wonders with most silver coins.
I found kraft envelopes and shoe boxes to be effective.
