I seem to recall that Holy Water requires a special blessing.
I quote a few relevant things from here.
In the older rite (which priests may still use and we should feel free to kindly ask them to do so), Holy Water actually received an exorcism (first salt is exorcised and then blessed, then, water is exorcised and then blessed), and the prayer recited "pour forth your blessing + on this element".
The difference of the new rite with the older rite is not just that there is no exorcism or blending of exorcised and blessed salt. There is not explicit act of blessing. There is no sign of the cross indicated in the text. The words don’t say the water is blessed.
So serious was this issue at many different levels (not just, clearly, with holy water) that in a decree ‘Urbis et Orbis’ on the 14th of September, 2002 , the Congregation for Divine Worship and the Discipline of the Sacraments established that the sign of the cross must be made by the sacred ministers in all blessings even if there is no indication in the text itself.
Therefore, if water is blessed with the newer rite, it may become holy water, but there is a serious theological doubt on whether it is also blessed water. Many priests overcome the issue by simply employing the traditional blessing.
Why were those changes made? I am not sure. :shrug:
THIS, by all means! Have the water and salt both exorcised, and the third blessing said over the mixture. It doesn't take much salt to make it work.
