You can get rid if the black stuff and water by opening the drain at the bottom of the tank and tilting it slightly to drain. Then pressurize the tank several times and open the valve. The air coming out may look clean but put you hand or a white rag in the air and you may still see black. After emptying the tank several times the air coming out will be clean. To convince yourself the black stuff is not getting into your lines just blow air from your hose into a white rag and inspect it afterwards. I flush the compressor tank just to remove moisture so the tank won't rust inside not because I worried about black stuff getting into the lines of the MH.
