Can I bathe my rats?

So I just got these two feeder rats yesterday and so far there very sweet for anxious baby's. I've been able to handle them and pet them and not once have they tried to bite me.

However they smell TERRIBLE. Like oh my God. I can barely smell my older boy, bit I can smell these baby's from like two feet away. It's bad.

Am I able to bathe them? And if so, what do I use? Just water?
