New Post: Delete ALL store contents (multiportal)

Hi there

I need to remove all the test products from a store and start fresh as I have made a bit of a mess of the products and categories testing CSV product import.

Can I use the "Delete ALL store contents" option (the one that requires host password) in the Admin section even if I have multi DNN portals and multiple NB stores on the other portals. I don't won't to give it a try if it is going to have an impact on other stores which are up and running and live...

Or can someone point me in the right direction to delete the products directly from the database?

Cheers
Bryan
