Uninstall RTC on AIX | Build Forge Automation Problem

We are developing connectors for RTC and as part of our continuous integration process we have to install/uninstall RTC on regular basis. We have been successful in automating the RTC install process through Build forge but are now stuck with the Uninstallation since its currently done through IM.

Can someone provide us the command line / script / ideas / folders to remove - which can do the job in a clean manner and make our process repeatable ?
