I know of two ways to clean /tmp after a reboot:


1) mount /tmp (and /var/tmp) as a tmpfs (in memory). Only use that if you
have enough RAM. I have 6 GiB. Put the following in /etc/fstab:

tmpfs   /tmp       tmpfs   rw   0   0
tmpfs   /var/tmp   tmpfs   rw   0   0

A variation is:

none    /tmp       tmpfs   size=2G,nr_inodes=200k,mode=01777   0   0
none    /var/tmp   tmpfs   size=2G,nr_inodes=200k,mode=01777   0   0


2) Add this to /etc/rc.local, just above "exit 0":

rm -rf /tmp/.* /tmp/*


Both methods are not Ubuntu specific, they work for all Linux distributions.
In other words: these are probably not the "Ubuntu recommended" methods.
But they work.
