A lot of our members say that all sands are just a matter of time and a little water expense. Ideally you have a bucket or other container large enough to allow plenty of water room beyond the surface of the batch of sand to be cleaned. In the back yard you shove the hose to the bottom of the sand and turn on the water lightly. You then tilt the bucket and prop it up such that the excess water is spilling where you want it to. You then adjust the hose flow such that you are not losing sand out the top of the bucket. Then you go off and do other things, periodically coming back to stir the sand and see if it's still producing lots of cloudiness. A good thing to remember with sand is that usually it's cheap enough that a little loss can just be made up with more sand, rather than adopting a worry attitide about all sand lost!
