Hi mibottles, welcome to the forum. Hydrochloric Acid gets into the stoneware deeper than the baking soda solution and would take months to neutralize it all (depending on the stoneware), it also gasses a lot where Phosphoric will do it's job then mostly soak out in the water bath then slowly reacts to a weak solution of Sodium Carbonate if it's needed. A big problem after soaking in Soda is getting the salt out of the item if left in it will slowly crystalize and destroy the item, this is why some things treated years ago start flakeing glaze or going powdery. Hydrochloric can also do some nasty things with various Oxide crud than can get into stone and create worse stains that you will never get out (I've been there done that ). I can strongly recommend that people only use Hydrochloric Acid on things it cannot soak into ie= glass . Hey wheelnuts, any chance of a photo of your one ? Should Travis, Anton etc. and I go pay a visit to Marrickville ? .
