Remove an instance from the SQL Failover Cluster

I have a two (2) node SQL Failover Cluster, and I had install an instance in my one of the SQL Failover Cluster node. For some reason I had to uninstall this instance but when I tried uninstalling through: Control Panel –> Program and Features —> Right click on Microsoft SQL Server 2012 (64 bit) and click remove, and it failed because when you try to remove it from Control Panel you get the following error:

In order to remove the SQL Failover Cluster Instance successfully use the following steps:

2.  Click on “Maintenance” in “SQL Server Installation Center”
