I only have one sink in my kitchen. Can I use it for both meat and dairy?

I only have one sink in my apartment. How do  I use it for both dairy and meat? This is a   very common question. In fact, there's a famous  yeshiva from Rav Moshe Feinstein that discusses   this question. And he says, that's okay, they  can use one sink for both meat and dairy, even   hot. But they shouldn't use it, obviously, at the  same time. What they have to do is, between uses,   clean it out. Especially the drain. You know,  if there's any meat or there could be any dairy   stuck in the drain, you should clean it out, wipe  around. You should also have separate racks that   go on the bottom of the sink, one for dairy  and one for meat. And then, once you do that,   you have a clean sink. Put the dishes on top of  the rack so it doesn't sit right on the surface   of the sink. Then it's no problem. You could  use the same sink for both dairy and meat.
