Here are the steps to clean up the private cloud 4.16.01.00 fresh installation setup:
1. Stop all the services running on all the box:
/opt/apigee/apigee-service/bin/apigee-all stop
2. Do yum clean to clear the yum cache
sudo yum clean all
3. Remove all the apigee|edge|bass RPMs
sudo rpm -e $(rpm -qa | egrep "(apigee-|edge-|baas)")
4. Remove the installation root directory
sudo rm -rf /opt/apigee
sudo rm -rf /opt/nginx

And finally, if required, remove apigee user from the OS.
/usr/sbin/userdel -r apigee
