Remove Variables on Script Completion

Hi,

Is there a way to remove variables that I create in a script after it has finished running. I have a script with a dozen odd variables which I would like to delete after the script has done its job.

The options I have seen are:

• Close down the Powershell environment and restart
• Use Remove-Variable command

If I use get-variable and limit the scope to script I see other variables which I did not define. I would only like to remove the variables which I have defined. 

Any suggestions would be appreciated. 

Regards,
