Actually what you need to do this job properly is
the "correct" tool, instead of just using any old
pencil eraser you need to use a genuine
"Carolina Tube Tapper".
These are available form the CC-AWA.
You can see them when you visit the CC-AWA
web page at http://www.cc-awa.org
and click on the "Goodies for sale"
button on the main menu.
