campus purchasing of cleaning supplies

If you can show a campus-wide green cleaning policy that complies with LEED-EBOM requirements then I don't foresee any trouble with LEED compliance.The one caveat I can think of is that you should demonstrate in some way that the specific project building gets the same green cleaning treatment as all the buildings. For example, if your policy were that 30% of cleaning product purchases were sustainable, but it happened for some logistical reason that 5% of the products actually used in the project building were sustainable, you wouldn't be meeting the credit intent or requirements.
