# Cleaning the Stoppers
### Cleaning the Stoppers
The bottle stoppers must be cleaned regularly to ensure optimal operation of the Velmix LQ.
Sweet alcohols tend to clog stoppers. The use of the " Stopper Cap " (AZC-501111) helps to block any air that might enter the stopper, thus reducing the risk of blockage.
Two cleaning methods are described below:
[Option 1](#onbottle): *Cleaning the stopper on the bottle*: to be used if the stopper cannot be removed from the bottle prior to cleaning.
[Option 2](#offbottle): *Cleaning the stopper with the stopper washer*: offers the best results and should be performed every time the bottle is changed.

### Cleaning the stopper on the bottle
**To clean the stopper while it is on the bottle:**
1. Open the hot water tap.
2. Let the hot water run for 1 to 2 minutes over the stopper while rotating the bottle.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.payfacto.com/payfacto-knowledge/veloce-pos/velmix-lq-232-ip/cleaning-the-stoppers.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
