Delete all files in /tmp except lock and socket files

Here's the deal. I'm in a SunOS, Irix, and linux environment. I'm trying to delete all the files in /tmp and /var/tmp that ARE NOT lock or socket files and are more that 30 days old. So far I got this:

find /tmp/ -type f -ctime +30 -exec rm {}\;
find /tmp/ -type d -ctime +30 -exec rm -r {}\;

These are just samples; but you get the idea.

Depending on how you can identify lock files, something like this:

 find /tmp -not -type s -not -name "*.lock"
