rust from concrete: 1) a solution called triple etch by Martin Senior pants or
called Metal Prep by Sherwin Williams. It is an acid (sulfuric or hydrochloric based
don’t remember which). You can also get the same type stuff at Home Depot. Look
for a solution used to clean Brick fireplaces, brick fascia, etc. Look on label
for contents to see if it is an acid based solution. <o:p></o:p></span></font></p>
