Phase 1: Preparation and Disassembly
Before beginning any cleaning process, proper preparation is essential to prevent damage and streamline reassembly. This initial phase focuses on safely disconnecting your keyboard and systematically removing its keycaps, ensuring you have a clear reference for putting everything back together.
Step 1: Disconnect the Keyboard
The very first and most critical step is to completely power down and unplug your mechanical keyboard from your computer. For wired keyboards, simply remove the USB cable. If you are using a wireless mechanical keyboard, ensure it is switched off, and if it operates on batteries, consider removing them to prevent any accidental power-on during the cleaning process. This crucial safety measure eliminates the risk of electrical shorts, static discharge, or inadvertent key presses while you are working with cleaning solutions and tools.
Step 2: Photograph the Keyboard Layout
With your keyboard unplugged, use a smartphone or digital camera to take several clear, high-resolution photographs of your keyboard's current keycap layout. Capture images from different angles, paying close attention to the arrangement of unique keys like the function row, number pad, and especially the larger, stabilized keys such as the spacebar, Enter, and Shift keys. These photos will serve as an invaluable visual reference when it comes time to reassemble your keyboard, preventing frustration and ensuring every keycap returns to its correct position. Organizing the removed keycaps by placing them in the same order on a tray or towel can also aid in reassembly.

Step 3: Remove Keycaps Safely
Utilize a keycap puller, an indispensable tool designed for this task, to carefully remove each keycap. Gently slide the puller's arms onto the north and south ends of a keycap until it securely grips the base. Then, pull straight upward with consistent, gentle pressure until the keycap detaches from the switch stem. It is important to avoid pulling too hard or using sharp objects like screwdrivers or knives, as these can easily damage the keycap, the switch stem, or even the keyboard plate. For larger, stabilized keys like the spacebar, Enter, and Shift, extra care is required; these often have wire stabilizers that need to be gently dislodged. Remove these stabilized keys last and note their orientation for easier reinstallation.
Phase 2: Cleaning the Keycaps
Once all keycaps have been safely removed, they can be thoroughly cleaned to eliminate the accumulated oils, dirt, and grime from daily use. This phase focuses on a multi-step process for deep cleaning the keycaps themselves, ensuring they are pristine and ready for reinstallation.
Step 4: Soak Keycaps in Soapy Water
Gather all removed keycaps and place them into a small bowl or container. Fill the bowl with warm (not hot) water, adding a few drops of mild dish soap. Hot water, especially for keycaps made of ABS plastic, can cause warping or damage. Allow the keycaps to soak for approximately 15 to 30 minutes. This soaking period allows the dish soap to act as a degreaser, breaking down and loosening stubborn oils, fingerprints, and other residues that have accumulated on the keycap surfaces. For heavily soiled keycaps, gently swish them around in the soapy water every few minutes to aid in dislodging grime.
Step 5: Scrub and Rinse Keycaps Thoroughly
After soaking, use a soft-bristled brush, such as an old toothbrush or a specialized keycap brush, to gently scrub each keycap individually while it is still submerged in the soapy water. Pay close attention to the sides, edges, and especially the underside where dirt often collects. For ABS keycaps, a soft cloth or sponge is recommended to avoid premature shine, while PBT keycaps can typically handle a soft-bristled toothbrush. Once scrubbed, rinse the keycaps thoroughly under clean, lukewarm running water to remove all traces of soap residue. It is crucial that no soap remains, as it can leave a sticky film when dry.

Step 6: Dry Keycaps Completely
Proper drying is arguably the most critical step to prevent moisture damage to your keyboard switches. After rinsing, shake each keycap gently to remove excess water droplets. Then, spread the keycaps out in a single layer on a clean, lint-free microfiber towel, placing them stem-side up to allow water to drain from the cross-shaped stems. Air-dry the keycaps completely at room temperature for several hours, ideally 6-12 hours, or even overnight. While some sources suggest using a hairdryer on a cool or low setting from a distance of 12 inches or more, air drying is generally the safest method, especially for ABS keycaps, which can deform under heat. Never reassemble your keyboard with damp keycaps, as trapped moisture can corrode switch contacts or cause electrical issues. Ensure thorough dryness by checking the inside of the stems, perhaps with a flashlight.
Phase 3: Cleaning the Keyboard Base
With the keycaps removed and set aside to dry, the keyboard's underlying plate and switches are exposed. This phase focuses on effectively removing debris and grime from these sensitive components, ensuring the mechanical integrity and responsiveness of your keyboard.
Step 7: Clear Loose Debris
With all keycaps removed, you will likely encounter a significant accumulation of dust, crumbs, and hair on the keyboard plate and around the switch housings. Begin by holding the keyboard upside down over a trash can or outside and gently shaking it to dislodge larger loose particles. Next, use short, controlled bursts of compressed air, keeping the can upright to prevent propellant discharge, to blow away dust and debris from between the switches. Angle the keyboard to allow gravity to help the debris fall out, rather than blowing it deeper into the switches or PCB. Alternatively, a soft-bristled brush can be used to sweep debris towards an edge, being careful not to press down on the switches and force particles inside. A small handheld vacuum with an anti-static attachment can also be effective for suctioning out debris without blowing it around.
Step 8: Clean Around Switches and Plate
Once loose debris is removed, focus on cleaning any sticky spots or ingrained grime on the keyboard plate and around the switch stems. Dampen a cotton swab or the corner of a microfiber cloth with 90%+ isopropyl alcohol (IPA). Ensure the swab or cloth is damp, not dripping wet, to avoid introducing excess moisture to the electronics. Gently wipe around each individual switch stem and the exposed keyboard plate, rotating the cotton swab frequently to use clean sections. Isopropyl alcohol is highly recommended because it effectively dissolves oils and sticky residues and evaporates quickly, minimizing the risk of damage. For particularly sticky switches, a minimal amount (1-2 drops) of 90%+ isopropyl alcohol can be applied directly into the switch housing, followed by actuating the switch 20-30 times to work the alcohol through and dislodge residue. Allow the switches to air dry for 10-15 minutes after this treatment. Avoid using alcohol on keycap legends, especially if they are painted, as it may remove the printing.
Phase 4: Reassembly
With both your keycaps and keyboard base thoroughly cleaned and dried, the final phase involves carefully reassembling your mechanical keyboard. This process requires patience and attention to detail to ensure every component is correctly placed, bringing your keyboard back to its optimal functional and aesthetic state.
Step 9: Reattach Stabilized Keycaps
Begin by reinstalling the larger, stabilized keycaps such as the spacebar, Enter, and Shift keys. Refer to the photographs you took in Step 2 to ensure correct orientation. These keys typically have small plastic inserts on their undersides that attach to metal stabilizer bars on the keyboard plate. Carefully align these inserts with the stabilizer bars and then position the keycap over its corresponding switch stem. Press down firmly and evenly until the keycap clicks securely into place and moves smoothly without wobbling. If you encounter resistance, do not force it; gently realign and try again to avoid bending the stabilizer wires or damaging the switch stem.
Step 10: Reinstall Remaining Keycaps
Once the stabilized keycaps are in place, proceed to reattach all the smaller, individual keycaps. Again, consult your reference photos from Step 2 to ensure each keycap is placed in its original position. Align the cross-shaped hole on the underside of each keycap with the cross-shaped stem of its respective switch. Apply firm, even pressure directly downward until the keycap snaps onto the switch stem. Listen for a distinct click, which indicates it is properly seated. Continue this process for all remaining keys, working methodically row by row to maintain organization and accuracy.
Step 11: Final Check and Test
After all keycaps have been reinstalled, carefully inspect your keyboard to ensure every keycap is correctly positioned and fully seated. Once satisfied, plug your mechanical keyboard back into your computer. Open a text editor or a keyboard testing utility and systematically type on every key, checking for proper actuation, responsiveness, and feel. Verify that there are no sticky keys, missed presses, or chattering. This final test confirms that your deep cleaning process was successful and your keyboard is fully functional, ready to provide that crisp, satisfying typing experience once again.
Common Mistakes to Avoid During Cleaning
Deep cleaning a mechanical keyboard can significantly improve its performance and longevity, but certain pitfalls can lead to damage or an ineffective clean. Being aware of these common mistakes can save you time, effort, and potentially prevent costly repairs.
One frequent error is spraying cleaning solutions directly onto the keyboard's base or switches. Liquids can easily seep into the sensitive electronic components beneath the switches, causing corrosion, shorts, or permanent damage. Instead, always apply cleaning solutions, particularly isopropyl alcohol, to a microfiber cloth or cotton swab first, ensuring it is damp but never dripping wet, before wiping the components. For keycaps, while soaking in mild soapy water is safe, avoid harsh chemicals like bleach, acetone, or general household cleaners, as these can discolor, degrade, or warp the plastic, especially ABS keycaps.
Another critical mistake is not allowing keycaps and switches to dry completely before reassembly. Even minimal residual moisture can lead to electrical issues or corrosion within the switches and PCB. Air drying for several hours, or even overnight, is highly recommended to ensure all components are thoroughly dry. Rushing this step by using high-heat sources like hair dryers can warp plastic keycaps, particularly those made of ABS. Furthermore, using sharp objects such as knives or screwdrivers to pry off keycaps can scratch the keycaps, bend switch stems, or damage the internal stabilizers. A dedicated keycap puller is specifically designed for safe and efficient keycap removal, minimizing these risks. Finally, neglecting to photograph the keyboard layout before disassembly is a common oversight that leads to significant frustration during reassembly, as remembering the exact placement of every key, especially non-standard ones, can be challenging.
Frequently Asked Questions
The frequency of deep cleaning depends on your usage and environment. For heavy users or those who eat at their desk, a deep clean every 3-6 months is recommended. For lighter use or cleaner environments, every 6-12 months should suffice. Regular quick cleans (weekly) and monthly regular cleans can reduce the need for frequent deep cleaning.
While 90%+ isopropyl alcohol (IPA) is generally recommended for cleaning electronics due to its faster evaporation and lower water content, 70% IPA can also be used effectively. The key is to apply it sparingly to a cloth or cotton swab, not directly to the board, to ensure minimal moisture introduction and quick drying. Avoid lower concentrations, as they contain more water which can increase the risk of damage.
No, it is generally not safe to put keycaps in a dishwasher. The high heat and harsh detergents used in dishwashers can cause keycaps, especially those made of ABS plastic, to warp, melt, or fade their legends. Hand-washing with warm water and mild dish soap, followed by air drying, is the safest and recommended method for cleaning keycaps.
If a key remains sticky or unresponsive, debris may be lodged deeper within the switch housing. Try removing the keycap again and applying 1-2 drops of 90%+ isopropyl alcohol directly into the switch, then actuate the switch 20-30 times to work the alcohol through. If the issue persists on a hot-swappable keyboard, replacing the individual switch may be necessary. For non-hot-swappable keyboards, professional repair or soldering might be required.
You can perform a quick surface clean without removing keycaps using compressed air and a microfiber cloth. This is effective for removing loose dust and surface grime. However, for a truly thorough deep clean that addresses ingrained dirt, oils, and debris under the keycaps and around the switches, removing the keycaps is essential.
Next Steps
After successfully deep cleaning your mechanical keyboard, you can enjoy a significantly improved typing experience with restored responsiveness and aesthetics. To maintain this pristine condition, consider establishing a routine of lighter, more frequent cleaning, such as weekly dust-offs with compressed air and regular wiping of keycaps.
