My preferred method is

cd /squid/cache
mkdir junk
squid -k shutdown
[wait for it to stop]
mv * junk
squid -z
squid
rm -rf junk

Pro/con
+ almost instant
+ disk space reclaimed quickly
+ No / or * in the dangerous rm -rf line
- some more commands to type
- silly warning about not being able to move junk into junk..
- Temporarily a high I/O load while removing the old files.

to avoid the warning you can use the following mv command

  mv swap.state* ?? junk

Or if the cache is on it's own partition, umount it, newfs and mount it
again.
