Lubricating your keyboard switches can improve the way you type and game, and even change the sound of your keyboard. This can be done by removing the keycaps and applying a thin, even amount of a suitable lubricant to the switch stems. The Krytox GPL-205 and GPL-105 lubricants are popular choices, but it's important to choose a lubricant that suits the type of switches you have. Once the lubricant has been applied, the switches can be reassembled and reattached to the keyboard.

What You'll Learn
Choosing the right lubricant
Type of Lubricant
The two main types of lubricants are grease and oil. Grease-based lubricants, such as Krytox 205g0, are widely regarded as the best option for keyboard stabilizers due to their thickness and durability. They are effective in making larger components, like space bars and enter keys, feel smooth without the risk of over-lubrication. On the other hand, oil-based lubricants are typically thinner and better suited for smaller components.
Compatibility with Plastic
It is crucial to choose a lubricant that is safe for use on plastic. Some lubricants contain petroleum distillates or other ingredients that can damage or dissolve plastic. Look for lubricants specifically labelled as "plastic-safe" or "safe for plastics." White lithium grease, for example, is commonly used inside talkers but may contain petroleum distillates, so it is recommended to opt for synthetic grease options.
Application Method
Consider the application method that works best for you. Some lubricants come in spray cans, making it easier to apply a light and even coat. Others might be applied with a brush or a dropper, requiring more precision and care to avoid over-lubrication. The Push-Stem technique is also an option, where you don't need to remove the switches from the keyboard, but it is only about 70% effective.
Keyboard Type
The type of lubricant you choose may also depend on the specific type of keyboard you have. Mechanical keyboards, for instance, have different lubrication requirements than traditional keyboards. Additionally, some lubricants are designed for specific switch types, such as linear or tactile switches.
Personal Preference
The choice of lubricant can also depend on your personal preferences regarding the feel and sound of your keyboard. Some lubricants may provide a smoother or quieter typing experience, while others may enhance the tactile feedback. Reading reviews and comparing different options can help you make an informed decision.
Remember, always follow the instructions provided by the manufacturer of your chosen lubricant and take your time during the application process to ensure even coverage.

Disassembling the keyboard
Before lubricating your keyboard, it is important to disassemble it carefully. Here is a step-by-step guide:
First, unplug your keyboard from the computer and ensure the power or wireless switch is turned off. Then, grab a keycap puller and place it over each keycap, pushing down so that the prongs clasp to the underside of the switch. Pull upwards to remove each keycap, exposing the keyboard switches. It is important to keep the keycaps safe in a box or tray so that they are not lost.
Next, you will need to remove the switches from the keyboard. For a traditional soldered mechanical keyboard, you will need to desolder the switches. Alternatively, for a keyboard like the Hexgears Impulse, you can simply pull the switches out with a switch puller.
Once all the switches are removed, it is time to disassemble them. Place each switch with the top face up and use a switch opener tool to unhinge and open it. Be sure to use a metal switch opener, as plastic or 3D-printed ones may not be stable enough. Take the different parts of the switch—the top housing, stem, spring, and bottom housing—and place them in separate containers for easy access during lubrication.
Now that your keyboard is disassembled, you are ready to begin lubricating the individual components. Remember to take your time and apply a light, even coating of lubricant.

Applying lubricant
To apply lubricant to your keyboard switches, you will need a lubricant suitable for mechanical keyboards, such as Krytox, Tribosys, or Permatex dielectric grease. You should also have a switch opener tool, a fine brush, tweezers, a clean cloth, and a well-lit, comfortable work area.
First, remove the keycaps from your keyboard. You can do this individually or all at once. You may also need to remove the switches from the keyboard, either by pulling them out or desoldering them. Be careful not to void the warranty by tampering with the keyboard.
Next, you can apply the lubricant. If you are lubricating springs, you can place them in a plastic bag with a few drops of lubricant, blow into the bag, seal it, and shake vigorously until the springs are coated. Otherwise, use a brush to apply a light, clear sheen of lubricant to the plastic, ensuring that it is evenly applied.
When lubricating the switches, focus on the key areas where the lower housing and stem make contact. This will reduce friction between the two. You can also lubricate the switch housing rails, stem sliders, and contact points. Be careful not to over-lubricate the stem, as this can result in air pockets forming.
Finally, reassemble the switches and put them back into your keyboard.

Reassembling the keyboard
Now that you have lubricated the keyboard, it is time to reassemble it. Here is a step-by-step guide on how to do it:
Firstly, place the bottom housing down, followed by the spring. Then, place the switch stem, ensuring that the legs are facing the gold leaves on the bottom housing. This is an important step as you must be careful not to bend the crosspoint contacts.
Next, place the top housing on top and push down until you hear it click back together. You can use a plastic tray to put the switch back together.
Once the upper and lower housings are snapped together, you can reinstall the switches on your keyboard. You can do this by pressing them or soldering them in position, depending on their type.
Finally, reconnect the keyboard and test the switches. You can use a free online tester called Key-test. It is important to test the keyboard before fully reassembling it, as it will be inconvenient to take everything apart again if there is an issue.

Testing the keyboard
Test Key Smoothness and Noise Reduction:
- Type on the keyboard and listen for any improvements in smoothness and sound. Pay attention to the feel of the keystrokes and notice if they are smoother and more effortless.
- Check for any remaining squeaking, rattling, or grating noises. Lubrication should minimize these unwanted sounds, providing a more pleasant and quieter typing experience.
Assess Key Functionality:
- Test each key individually to ensure they are functioning properly. Press each key a few times to check for consistent key presses and accurate registration of inputs.
- Look for any signs of "key chatter," where a single key press registers multiple inputs. Lubrication should help prevent this issue by reducing stickiness and improving the reset of the switches.
Fine-Tune Lubrication:
- If you notice any inconsistencies in smoothness or noise after initial testing, you can fine-tune the lubrication.
- Adjust the amount of lubricant applied to the switches and stabilizers. Add or remove small amounts as needed to achieve optimal performance.
- Test the keyboard periodically after adjustments to achieve consistent results.
Monitor Long-Term Performance:
- Regularly monitor the lubrication on your keyboard, especially with frequent use.
- Periodically check the stabilizers and adjust them if necessary to maintain key stability and reduce any potential rattle or noise.
- Reapply lubricant every six to twelve months, or sooner if you notice any changes in sound, smoothness, or functionality.
By following these testing and maintenance steps, you can ensure that your keyboard provides a comfortable, smooth, and quiet typing experience, while also prolonging its lifespan.
