How to set up cron job in Linux to delete all regular files?

I need to set up a job to delete all of the regular files in the /home/admin directory on the second day of every month at 8:30 A.M.
It seems like wrong command:

# crontab -e
30 08 02 * /bin/find /home/admin -type f -exec /bin/rm {} ";"

Help please.
