What do most teens my age wash their face with?

i'm 16, i don't really get much acne but i have a couple of spots but they go away every few days. but at nights before i go to bed, i just rinse water on my face and get rid of the oil and other crap that was on it. and i dab it with a cloth and i go to bed... should i actually be washing it with chemicals and other crap? what do you guys use on your face before you go to bed? i'm not looking for some acne crap because i don't need it, i'm just curious if i need like a face cleaner if that makes sense.
