Deleting Multiple Contact records

Content

Hi all,

I'm a novice when it comes to this aspect of Service Cloud, but hoping to learn... I have spent hours reading the documentation, trawling posts & discussions, and using a certain amount of trial & error - but to no avail. 

We have a need to delete around 50,000 Contact records. As far as it goes, it has been thought out and there is a reason to delete these, rather than have them go dormant. We have a custom report that can be run to obtain a list of the Contact IDs - but I want to know how to delete the records without having to go through and manually delete them from the report 250 at a time!
