What is the best method of applying muratic acid? I have been using some of the nicer pump up sprayers with mostly all plastic parts, but they don't last long. I have seen some guys run it through their x-jet, but I didn't see if the x-jet survived... I would love to find a 'safer' chemcial, but I havn't found anything better to take the red clay and mud that we have here out of concrete.
