# Cleaning the Smart Dispenser O-Ring

#### When to Clean the O-Ring

Clean your smart dispenser O-Ring every time you notice material build up around the O-Ring when disassembling the smart dispenser. This should be done on an as needed basis, but it is worth inspecting after each use. Usually there will be other signs like a ruptured cartridge to let you know this needs to be done.

#### Steps for Cleaning the O-Ring

**Step 1:** Wear appropriate PPE. Refer to the SDS of your material. Typically, this means gloves and goggles, and sometimes requires handling in a fume hood.

**Step 2:** Remove the O-Ring by rolling it up and over the groove. Then gently wipe down the O-Ring with isopropyl alcohol and a low-lint wipe. This is also a good time to inspect the O-Ring for any damage or swelling.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.voltera.io/docs/nova/learn-nova/general-maintenance/cleaning-the-smart-dispenser-o-ring.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
