What can I use to bring my brick walkway back to life?
We dug up a brick walkway and would like to reuse the bricks but they are dingy. Pressure washing did not do the trick.
A possible solution would be applying Prosoco, Inc.'s Enviro Klean® Safety Klean per the manufacturer's recommendations.
This product is an alternative to acidic compounds for cleaning brick surfaces.
Note: Do not use acid to clean bricks. It will remove the outside layer and expose the more porous interior, which will allow the bricks to absorb more moisture and hasten cracking during freeze/thaw cycles.
Hope this helps.
