You should not wash fresh lettuce or other lettuce before storing as washing lettuce before storing adds moisture to the lettuce which leads to spoilage.
Always store your fresh lettuce dry to make it last longer and less oxygen exposure to the lettuce will keep the lettuce fresh longer so it's best to store your lettuce in plastic containers or plastic bags for long term storage.
To properly wash lettuce start by placing the lettuce leaves in a sink and swirling them in water and then soak the lettuce leaves for about 10 minutes and give them a good swirl every few minutes.
The dirt and grit on the lettuce will then sink to the bottom of the basin and then you also rinse off the lettuce afterwards.
You should wash your lettuce in water and soak them in a bowl of water and then rinse them off under cold water in the sink and pat the lettuce leaves dry before storing them.
You can fill a large bowl with water or your kitchen sink as long as it's clean and soak your lettuce in the water that way.

To keep your salad fresh in a container layer the bottom of the container with paper towels.
The paper towels will absorb moisture.
Then, gently pack the leaves in the container and top with another paper towel before storing in the crisper drawer.
Don't pack the leaves too tightly, or they will not have breathing room and that can invite rapid rot.
Lettuce requires a good amount of airflow, in addition to a bit of moisture (but not too much!), in order to stay crisp.
That's why restaurants will store their lettuce in special perforated bins that allow for air circulation while it's held in the fridge.
