The question is, why? It’s a black tank that will always be nasty, so why clean it so you can just make it a black tank again? Just use a quality enzyme treatment between dumping and you should be good. Depending on how big the tank is, you would need maybe up to 50 gallons of vinegar, and then, what do you do with it when you are done?
