# Cleaning Saline Sensors

Saline sensors should **only** be subjected to saltwater while they are in use. After use, you must rinse the sensors with clean water to remove the salty residue. Doing this will prolong the life of the sensors. After rinsing, dry the sensors with a towel or tissue. &#x20;

### Saline Sensor Felts Warning

Do not leave the sensor felts in the saline sensors. Leaving wet sensor felts in the saline sensors will corrode them. Store used sensor felts separately from unused ones.&#x20;

You can purchase replacement sensor felt packs from the EMOTIV [online store](https://www.emotiv.com/product-category/accessories/). &#x20;

## 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://emotiv.gitbook.io/flex-2.0-user-manual/cleaning/cleaning-saline-sensors.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.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
