Do you still owe them any money? They likely won’t redo the plaster unless you owe them a decent amount of money still.

Apparently, the PB doesn't realize that all of the plaster is submerged in water and absorbs water. (Yes, sarcasm) And the plaster will begin to lose water (evaporate and dry out) when it is drained. And it will absorb water again when submerge again.
And apparently, the PB doesn't know that the Portland Cement Association has documented that gray mottling discoloration is caused by several mistakes when plastering. Perhaps, he should do some reading about cement and plaster issues.
But regardless of that, acid treatments will etch the plaster surface, make it rougher, and that in turn, can lighten the color of the surface. So it can appear that the grey discoloration is being removed. That is what the PB is hoping for, and that you can be convinced that he fixed and removed the graying.
I suggest trying whatever you can to closely document the present smoothness of the plaster surface prior to the PB's acid wash, that you will not tolerate a rough and etched surface.
I would also insist that the judging of the results (of the gray color removal) to be held off for at least 3 months afterwards. Often the gray discoloration will return again in a few months.
And as @kimkats often mentions, get it in writing.

What @onBalance said! Get it all in writing. "Dear PB, On ?day you and I talked about xyz....." kind of thing if he tries to just phone call you are talk in person.Send it read/receipt.
