How to wash clams:

If there is enough time

Clams belong to shellfish, the more common cleaning method is to put the clams in water, add salt in moderation. Leave them like this for a night's time, and basically the sand is spit out.

If you're short on time

If you don't have as much time as you'd like to deal with the ingredients, you can do it the following way: put the clams in lightly salted water and keep stirring clockwise (the direction can't be messed up), and then replace the water with fresh water, stirring in the same way, and cycling through the process a couple of times, alternating between salted and fresh water until the water clears up and there's no sand in it.
