In the 70's I made stainless tanks & sinks for film developing.
To get the gold - brown weld marks off we would use Lionel train transformer wet rag with passivation acid backed by copper rod or sheet
Ground transformer to sink other positive wire to copper rod move rag backed by copper along weld worked great
