Yes, the calcium would still be there, but I thought the vinegar would change the chemical composition and let it be "suspended" or become solid in the water.
Does anyone know if such a mild solution (10 gallons of 9% vinegar in ? 500 ? gallons of water) would dull the finish?
And would it even begin to REMOVE the residue (depending on what it is, of course) from the side of the tub?
