If they are real dirty you can pull them off and let them soak in some fuel injector cleaner and then dig around in them with a unfolded paper clip. I wouldn't submerge the electrical connections though. They probably don't like that too much.
If You're just looking for a product to dump in the gas tank you will be happy with Chevron's fuel injector cleaner. Any brand is probably ok, however.
On a 2010 your injectors probably aren't too backed up though.
