Is this flirting?

One of my coworkers I suspect is flirting. We get along pretty well, I noticed that she tries to "clean me up" sometimes. Brushing dust off my shirt, messing with my hair if I have some gel specks, and taking them off I wanted to know if you guys think this is flirting?

She makes several quips as well, in passing as we work. She also said she would bang if she didn't have a boyfriend, but she wouldn't because of that reason.
