Yes, it's easy to do.

The bow hairs can stick together, or it's just cranky and doesn't seem to sound right. I'm sure you'll get a better description than that.

Solutions- One possibility (I've never done this with a good bow- just a cheapy Glasser bow I had for my kids)

You can loosen the bow and take the frog off of the stick, then very carefully wash the hair with a gentle soap and water. On the other hand, it might just be time to get the bow rehaired. When the bow isn't behaving, and you keep putting rosin on, it might be that the rosin doesn't stick anymore. A bow rehair costs about $30 here.

I'll be interested to hear what other people say.
