You can use drain. We use drain when talking about removing liquid from something. We use strain to remove solid things from something. 😊

Hello! To "drain" something is to let out the water so that it dries for example a bath or sink. To strain something is to pour a mixture of liquids and solids through something, like a colander, which has holes or small openings that will allow the water through but not the solids. In this way we are separating the solids from the liquids.
