Stir gently with same wooden spoon or any flat smooth utensil for about 3 minutes, to wash the mud off the crawfish’s shells and gills.

Discard the salt water, by completely draining it out.

Drain them as needed, so you aren’t leaving them submerged in water. Be sure to remove the ice and let the crawfish return to room temperature before purging and cooking.
