Re: Hello to Hookahpro
Slightly off-topic, but Hajo what about something like this: http://www.cpapusa.com/item.php?productcode=cpapdryer%20(3%20lengths)&nam e=CPAPDryer+Tube+Cleaner
It's used to clean CPAP hoses, it would need a thinner weight (check the fishing section) and perhaps cutting the fabric edges down alittle, but it should work. And it coming in a length to work on 10 foot hoses.
