How to remove all the item - vendor prices?

@Edgar Valdes saved search to bring all items, vendors, vendor code, and if they are preferred or not. Then csv import that file to update all items and set the vendor price to 0. Map all columns from the search and hard code the vendor price to 0.

Doing so set the price at 0, but the item-vendor relationship persist. Anyway to remove it?

script definitely would do the trick, but I think csv import with overwrite sublist could clear all vendors from an item.
