There was a thread about this on a welding forum I'm on.

Several people reported success using 12V power supplies with the positive connected to the work, and the negative connected to a conductive brush, something like https://www.ebay.com/itm/Qty-1-Pure-...B/263542164351. For the cleaning solution, they used 1 part phosphoric acid to 3 parts water.

I've not tried it personally, as I rarely work with stainless, but the results looked impressive.
