# 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.
