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.

Bung it in a concrete mixer for a few rotations? Pour out through a
suitably sized sieve, over a container for the water (barrel?) bucket
some of the water back from the barrel to the mixer and add a bucket
of clean. Excess water will overflow and drain away.
