I have tried dropping through a length of kite string or fishing line attached to a nail, and then pulling a piece of cloth through with that, but it really doesn't seem to be worth the effort when I use a 5 ft tube @ 10p/ft.
Wash / disinfect immediately after use, whirl dry and hang up.
I usually have a couple in service and a new spare in my bits box, then they get replaced as soon as they start to look tatty.
