reset votes for k2 items

How can I reset the votes for all my k2 articles?
I found this but did not work for me and I feel I can do something wrong:

Any easy way to do it?

Hi,

This is a tutorial for Joomla! com_content component not K2.

Please also remember that in K2 you can open the item editor and on the right sidebar you will have a "reset" button for the item rating.

Thanks. That was an easy one:) Just how I like it.
