Looking at streetview of dirty driveways in my area, I saw this:
Let's say I went in and cleaned the driveway and it looked great (obviously this particular example is really discolored already), I would imagine a lot of stuff (dirt? sand?) would become dislodged from the areas between the bricks. Are you supposed to lay down new sand to fill these gaps when you are done? Or do you just clean it and leave?
