For large amounts of it, a big rubbermaid can with a garden hose outside.
I've used a 5g bucket next to the kitchen sink. A short length of hose constantly siphoning water (and floating dust) out into the sink, the faucet on and off, depending on water depth, and stirring regularly.
I've also used a small-ish steel mesh colander in the sink with the faucet nozzle on "spray". It takes a while, but a couple beers and an IPod work wonders.
