question

Good morning all! Well my Griffin is almost 8 weeks old now and he's growing like a weed. I'm getting pictures shortly so I'll be sure to post soon. Anyway, I have a question about how to keep the folds in his smushy little face clean. He has some deep creases and I noticed they are getting dirty. Is there some sort of skin cleanser, aside from bathing him, that I can use with a q-tip or something? Any suggestions? I don't want his face to get all those red, infected lines.
