+## Cleaning sample application from cluster
+
+1. Delete the scaled object and order-processor application.
+
+    ```text
+    # kubectl delete scaledobject cosmosdb-order-processor-scaledobject
+    # kubectl delete deployment cosmosdb-order-processor
+    ```
+
+1. Optionally, delete the external scaler and KEDA from cluster. The following commands assume that KEDA was installed with Helm.
+
+    ```text
+    # kubectl delete service cosmosdb-scaler
+    # kubectl delete deployment cosmosdb-scaler
+    # helm uninstall keda --namespace keda
+    # kubectl delete namespace keda
+    ```
+
+1. The monitored container can be deleted with the below command. The lease container can be deleted on Azure Portal.
+
+    ```text
+    # docker run --env CosmosDbConfig__Connection="<connection-string>" --interactive --rm --tty cosmosdb-order-generator teardown
