It happens, one can live the whole life and not learn how to wash the salad properly: you turn on the hot water and put the salad under it to rinse. Hot water, under pressure, breaks the leaves. Now it can no longer be called a salad. Next time, take a large deep container, take cold water, put the salad in and let it sit for about 10 minutes. Then gently take it out and dry it on a paper towel or in a special salad spinner.
