Suppose that you want to test the effects of different dishwashing detergents on dishes that have food stuck to them. To test the differences, you wash three loads of the same dishes, each with a different type of detergent, all in warm water. You also wash a fourth load of dishes with only warm water.

I think that the question here is: which one is the control for the experiment?

The answer is the load of dishes with only warm water. A control condition in an experiment helps compare the influence of the variable that we're focusing on to the state without this influence.
