Cleanup needed after removing vMA prior to deleting targets

vMA 4.1.0 BUILD-268751

I removed my vMA prior to removing it targets.  Is there a preferred way to cleanup the residual "vi-admin00" and "vi-user00" account information on the esx hosts prior to deploying a new vMA?  Also, is there any residual information left over in regards to vCenter since I registered vCenter as a target.

The vMA documentation states:  IMPORTANT If you delete vMA without removing all servers, the vi‐admin and vi‐user users remain on the target ESX/ESXi hosts. The next time you add the host to a vMA instance, vMA creates a user name with a different numeric extension.

Thanks.
