To clean little neck clams so they’re not gritty, you need to (1) scrub the shells under cold water and (2) soak them in cold salted water so they purge sand from inside.

Basic prep steps

  • Discard any clams with cracked shells or ones that stay open even after you tap them; those are likely dead and unsafe to eat.
  • Rinse all the clams under cold running water, rubbing them together with your hands or using a brush or stiff paper towel to remove mud and surface grit from the shells.

Salt water soak (purging sand)

  • Mix about 4 cups of cold water with 1–2 tablespoons of kosher salt to mimic seawater; stir until the salt dissolves.
  • Place the clams in a bowl with this salted water and let them soak so they can spit out sand and grit; most home cooks use 20 minutes to 2 hours, depending on how sandy they are.

Handling during the soak

  • Keep the bowl in the fridge or a cool spot while they soak, and cover loosely so they’re in a dark, quiet environment, which helps them open and purge.
  • After soaking, lift the clams out of the water (do not pour them out with the dirty water) so the sand that settled on the bottom stays behind; then give them a final quick rinse.

Safety and cooking tips

  • Cook clams within a day or two of purchase and keep them in the fridge covered with a damp towel, not sealed in airtight plastic, so they can breathe.
  • When cooking, discard any clams that do not open after steaming, as this is a sign they were not healthy.
