The reaction described here is in a basic solution, not acidic, with ample free Fe. Therefore, I believe, from considering the chemistry of Cr6, if any present, it would combine with the Fe as follows, and become harmless Cr3.

Cr6+ + 3Fe2+ → Cr3+ + 3Fe3+

Cr3+ + 3 OH → Cr(OH)3

Fe3+ + 3 OH → Fe(OH)3

Making the spent solution even more basic (with soda lime)
CaOH, would ensure no Cr6 is present; but perhaps this step isn’t necessary.
Using Cr in the reverse polarity direction (Negative to stainless steel), in an acidic solution would INDEED produce the Cr6 ions that you are concerned about.

Since I’m a cheapskate, I usually dry with a rag and immediately ‘oil’ the piece. Cheap spray Canola oil works best!

It can easily rust and become dull.
