        I believe vinegar is largely Acetic Acid. I do not think you are
actually neutralizing the Phosphoric acid, but probably diluting it enough
so it doesn't react badly later....

Vinegar is a great neutralizer of phosphoric acid...  I use OzPho and follow

up with Vinegar..  Heck, for a gas tank I take all of mine to the muffler 
shop and let 'em soak overnight in their vats..
