May I ask why? Snakes don't generally need baths at all, let alone one with soap of any kind. And as gentle as Dawn is, it could be dangerous if it gets up in the snake's nostrils or ingested (which often happens when a snake is in water). Although Dawn is often used by wildlife officials to clean animals that get caught up in oil spills, etc, caregivers are extremely careful to avoid getting it in the animal's mouth and nose. I'm not being critical, but there are many folks here who are new or might not understand. If you have a particular reason for doing this, please explain. Thank you!
