Well, to my mind, grinding on a glass plate is much too messy, requires too much work, and
if way too "iffy" for me. It is too easy to ruin crystals.
I prefer to etch my crystals to frequency.
As I and one or two others here have mentioned, use Whink Rust Remover. That has 1% HF
in it. It does the job just fine, although at that concentration, it is slow. But in this case, "slow"
is exactly what you want.
