Is there a cost effective way of washing gravel? I've tried putting it
in a handheld steel sieve sloshing it around in wheelbarrow of water,
but that was very slow, and generated large quantities of muddy water.

I suppose I could just put a membrane on top of it, followed by more
gravel, but I'd like to re-use the existing stuff.


You don't need to wash it. Simply use a sieve with a mesh size slightly
smaller than the gravel and sieve the dirt out. It is time consuming and
you will end up with a surprisingly large pile of dirt, but it works.
