Your farm fresh greens (spinach, lettuce, arugula, Asian greens, etc.) will appreciate a good washing. Best practice is to do this right before you use it. Make sure that your greens come from a trusted source like LotFotL Community Farm that uses good food safety practices to ensure veggies are free from contamination.  Use a sink or container that is good and clean and choose clean fresh water.

Fill basin with fresh clean water

• Soak greens and agitate the water well with your hand to knock off any dirt or debris (greens are happiest if only soaked for about 1 minute or less).  Some people like to add their veggie wash at this time, others, like us here at the farm, feel fine with just plain clean water.
  
• Scoop the greens out of the water into a strainer, leaving any sand or dirt to settle to the bottom of the water basin. (Scooping instead of dumping helps keep the sand in the water and off from your food).
  
• If needed, send your greens through a salad spinner to help them dry.
