My water change hose has turned almost black over the many years of using it for maintenance. It's the Python tubing and probably at least 40-50'. Any suggestions on how to clean this? Or is it time to invest in new tubing? Even after so many years it is still flexible, so I would hate to just toss it.
Would it help to leave it in the sun? I may try to thread a string through it a few times with a tubing brush at the end.
