About the dirt, a bit of code form Gilles Tran:

"The little function below (or variations thereof) gives nice dirt streaks
when applied over a texture :
pigment{
         function {min(1,max(0,y))}
         turbulence 0.5 lambda 3 poly_wave 2 scale <0.1,1,1>
         color_map{ // or pigment_map
                 [0 Black]
                 [1 Clear]
         }
}
Unlike gradient, it's not repeating and unlike planar it's not symmetrical,
which means that the streaks extend in the positive y direction only (in
this case). It's much easier to control too. I've been using it to darken
and add streaks to tops or bottoms of walls, corners or edges of sidewalks
etc."

Hope this helps.
