Stuff a pipe cleaner into the tube. I works a bit longer.

longer than totally clearing the tube??? I don't think so. And the
pipe cleaner can bet "glued in" by the foam too. When I rinse with
acetone and blow the tube out, it's pretty much as clean as new.

Pick your poison. Can't speak for everybody. YMMV
A "clean " tube will be useable any time from 5 minutes from now to 5
years from now.

A pipe cleaner can be stuck in, never to come out again - or might
come out with a lot of pulling.

Bailing wire does the same as the pipe cleaners.
