Cleaning Tips for PBT and ABS Keycaps

Keeping your keycaps clean is essential to maintain the aesthetics and longevity of your mechanical keyboard. PBT (Polybutylene Terephthalate) and ABS (Acrylonitrile Butadiene Styrene) keycaps have different properties and require specific cleaning methods to avoid damage and ensure optimal performance. In this guide, we'll provide the best cleaning tips for both PBT and ABS keycaps.

Understanding PBT and ABS Keycaps

PBT Keycaps:

• Known for their durability and resistance to wear.

• Have a textured feel and are less prone to shine over time.

• More resistant to heat and chemicals compared to ABS.

ABS Keycaps:

• Typically have a smoother texture and are more affordable.

• More susceptible to developing a shiny surface due to finger oils.

• Can fade and yellow over time, especially with exposure to UV light.

General Cleaning Tips

Regardless of the material, regular cleaning helps extend the lifespan of your keycaps:

1. Dust Removal: Use a soft brush or compressed air to remove debris from between the keys.

2. Wiping Down: Use a microfiber cloth slightly dampened with water to clean surface dirt.

3. Deep Cleaning: Perform a deep clean periodically by removing the keycaps and soaking them in warm, soapy water.

Cleaning PBT Keycaps

Due to their durability and resistance to chemicals, PBT keycaps can be cleaned with:

• A mild dish soap solution for deep cleaning.

• A soft-bristled toothbrush to gently scrub textured surfaces.

• Isopropyl alcohol (70% or lower) to disinfect without damaging the material.

Steps to Clean PBT Keycaps:

1. Remove keycaps from the keyboard using a keycap puller.

2. Soak them in a mixture of warm water and dish soap for 30-60 minutes.

3. Scrub gently with a soft brush.

4. Rinse thoroughly and allow to air dry completely before reinstallation.

Avoid: Harsh chemicals or excessive scrubbing that might erode the keycap legends.

Cleaning ABS Keycaps

ABS keycaps require a gentler approach to prevent premature wear:

• Use a mild soap solution with lukewarm water.

• A soft cloth or sponge to gently wipe the surface.

• Limit exposure to harsh cleaning agents as they can cause discoloration.

Steps to Clean ABS Keycaps:

1. Remove keycaps carefully with a keycap puller.

2. Wash gently using a mild soap solution.

3. Wipe with a soft cloth to remove stains.

4. Dry completely before placing them back on the keyboard.

Avoid: Prolonged exposure to sunlight and alcohol-based solutions, which may accelerate yellowing and shine.

Preventive Maintenance

To keep your keycaps clean for longer, consider these preventive measures:

• Hand Hygiene: Wash your hands before using the keyboard to reduce oil buildup.

• Keycap Pullers: Use a proper keycap puller when removing keycaps to avoid damage.

• Storage: Store extra keycaps in a cool, dry place away from direct sunlight.

Conclusion

Regular cleaning of your PBT and ABS keycaps is crucial for maintaining their appearance and functionality. By following these simple yet effective cleaning tips, you can enjoy a clean and visually appealing keyboard for years to come. Whether you have durable PBT keycaps or smooth ABS keycaps, taking the time to care for them will always pay off in the long run.
