I cleaned some box steel with muriatic acid so as to clean off the mill scale. The parts will be used for a welding table. Working outside I poured the acid straight (not diluted) into a small container and used a foam brush to smear the acid onto the metal and then used a scotch bright pad with the acid to rub off the black and surface rust. I then only sprayed down the parts with water...now is there a next step??? Other than rinsing with water is there any other other cleaning/neutralizing I need to do? Yes I read on line to make sure to put the cap on the bottle and not have any acid/ brushes in my metal building... THANKS!!!
