releasing your work

Hoping someone can help,

I have a repository for a web application. It has lots of testing files 
and also others from caching and dynamic content generation (they are 
gitignored).

How do I make a "release" a copy (not a clone) of the repository that 
contains only tracked files without .gitignore files? I am using git 
archive but the resulting zip file still contains .gitignore files.

Cheers,
Lucas.
