Sir:

I would like to clear the software inventory and have the scan start fresh.

I’ve seen lots of people ask how to do this but I haven’t found a a post on how to do it.

Just removing software, while leaving the devices is not currently possible. You can remove all the devices though, and the software/services/hotfixes will be removed as well.

Then run a new scan to get everything back.
