## Cleaning up Nodes
<Tabs groupId="k8s-distro" queryString>
<TabItem value="RKE1">
Before you run the following commands, first remove the node through the Rancher UI.
To remove a node:
1. Click **☰** and select **Cluster Management**.
1. In the table of clusters, click the name of the cluster the node belongs to.
1. In the first tab, click the checkbox next to the node's state.
1. Click **Delete**.
If you remove the entire cluster instead of an individual node, or skip rermoving the node through the Rancher UI, follow these steps:
1. [Remove](#docker-containers-images-and-volumes) the Docker containers from the node and [unmount](#mounts) any volumes.
1. Reboot the node.
1. [Remove](#directories-and-files) any remaining files.
1. Confirm that network interfaces and IP tables were properly cleaned after the reboot. If not, reboot one more time.
### Windows Nodes
To clean up a Windows node, run the script in `c:\etc\rancher`. This script deletes Kubernetes-generated resources and the execution binary. It also drops the firewall rules and network settings:
```
pushd c:\etc\rancher
.\cleanup.ps1
popd
```
After you run this script, the node is reset and can be re-added to a Kubernetes cluster.
### Docker Containers, Images, and Volumes
:::caution
Be careful when cleaning up Docker containers. The following command will remove *all* Docker containers, images, and volumes on the node, including non-Rancher related containers:
:::
```
docker rm -f $(docker ps -qa)
docker rmi -f $(docker images -q)
docker volume rm $(docker volume ls -q)
```
### Mounts
Kubernetes components and secrets leave behind the following mounts:
* `/var/lib/kubelet`
* `/var/lib/rancher`
* Miscellaneous mounts in `/var/lib/kubelet/pods/`
To unmount all mounts, run:
```
for mount in $(mount | grep tmpfs | grep '/var/lib/kubelet' | awk '{ print $3 }') /var/lib/kubelet /var/lib/rancher; do umount $mount; done
```
