Uninstalling ELK Stack

How to uninstall Elasticsearch, Logstash and Kibana individually?? Is there anyway to uninstall ELK Stack at once??
I am using ubuntu 15.04 OS Looking forward for quick response

There's no special uninstall procedure at play here. Uninstall software in the same way as you once installed it, except the other way around. If you installed the Debian packages then use apt-get remove or apt-get purge and if you ran it by unpacking tarballs delete the directories. Things like log files and ES's data directory could be left behind and require manual deletion.
