This article will introduce in detail how to clean the graphics card slot and provide structured data to help you complete the cleaning work more efficiently.
1. The necessity of cleaning the graphics card slot

The graphics card slot (PCIe slot) is an important component that connects the graphics card and the motherboard. After long-term use, dust, oxidation or foreign matter may cause poor contact. Regular cleaning can:
1. Improve graphics card stability
2. Avoid performance degradation caused by poor contact
3. Extend hardware life
2. Preparation of cleaning tools
Here's a list of tools you'll need to clean your graphics card slot:
| Tool name | Purpose | 
|---|---|
| compressed air tank | Blow away dust from the slot | 
| soft bristle brush | Gently brush away stubborn dust | 
| Absolute alcohol (99% concentration) | Clean oxidation or stains | 
| Cotton swab or non-woven fabric | Wipe the inside of the slot | 
| Anti-static bracelet | Avoid static electricity damaging hardware | 
3. Cleaning steps
1.Power off and remove the graphics card
Turn off the computer and unplug the power cord, press the buckle of the graphics card slot, and gently pull out the graphics card. Be careful not to use excessive force.
2.Initial cleanup
Use a can of compressed air to blow the slots from different angles to blow most of the dust out. It is recommended to operate in a well-ventilated environment.
3.deep cleaning
