Hey everyone, today I want to walk you through how to clean the Yocan Uni 4.0.
If you've been using yours for a while, you've probably noticed a drop in flavor, weaker vapor, or the cart not making great contact. Most of the time, it's not the device — it just needs a good clean. Regular maintenance keeps the flavor consistent and extends the life of your device.


Here's the cleaning routine I use. It's quick and easy:
1. Power off first
Press the power button 5 times to turn the device off. Don't skip this — safety first.
2. Remove the cart
Take the cart off the device and set it aside.
3. Start cleaning
Dip a cotton swab in a little alcohol and clean the connection points and threaded connection. These are the spots that collect residue and affect contact the most.
For the body, wipe it down with a soft cloth. Don't rinse it with water, and don't let alcohol seep into the device.
4. Let everything dry completely
Make sure all parts are fully dry before reassembling and using. Don't rush this — leftover alcohol can affect the taste and damage the device.
5. Clean regularly and replace the cart when needed
Get into the habit of cleaning regularly, and don't push a cart past its lifespan. If the flavor tastes off or the vapor drops noticeably, that's usually your sign to swap it out.
That's it — follow these steps and your Yocan Uni 4.0 will keep performing the way it should.
