Rinse it! Rinse it! Rinse it! And rinse it some more! Don't breath in soapy tasting mist into your lungs! If you can taste any soap, even if only a hint of it, rinse it under gently running water again. As many times, for as long as it takes, under *gently* running water.
Breathing in an emulsifier (soap) into your lungs could be detrimental to you. And its an easy problem to fix. :-) (voice of experience).
Be sure and tap your harp out after rinsing it, before you test draw. If its a wood comb, let it dry completely.
