Do you need to rinse your recyclables?

Ask Umbra at Grist answers a reader's question about whether they should rinse out their recyclables.

As a California resident, ... I’m torn: Do I waste another gallon of water trying to get those last remnants out of the Sriracha bottle or do I save the water and recycle a less-than-pristine item?

Umbra's response, as usual, is well worth reading.
