Question
I have recently removed some shrubs and replanted several arbovitaes.  In the process, I removed a weed barrier that was covered in rock that was full of dirt, debris, and mulch.  I would like to reuse this rock now that my new plants are in.  Is there any way to clean this rock to eliminate all the extra junk.  I have tried sifting it (facilitated by washing it down with a hose) with an old screen from a screen door and drilling holes in the bottom of a bucket, but neither seems to be able to get rid of the excess adequately.  Any ideas?

Answer
Shane,

When I did this, I washed the rock in a bucket, but with no drain holes.  I used a strong hose and a stick to keep the pot stirred and overflowing until the water ran clear.  The debris floated away with the overflow.

For what it's worth,
