How to Clean a Mechanical Keyboard: Step-by-Step Guide

Quick Answer

To clean a mechanical keyboard properly, unplug it, flip it to shake out crumbs, vacuum or air-blast the gaps, pop off keycaps and soak them in warm soapy water, wipe the switch plate with isopropyl alcohol, then dry everything fully before reassembling. The full process takes 30 to 45 minutes for a deep clean, with a quick weekly surface clean taking under 10 minutes.

Tools and Supplies You'll Need in SA

Most of what you need is already at home. You want a keycap puller (every Evetech-stocked board ships with a wire or plastic puller), a soft-bristle brush, microfibre cloths, isopropyl alcohol of 70% or higher, dish soap and a can of compressed air. SA-specific tip: brake cleaner and contact cleaner are not safe substitutes, they can dissolve switch housings. If you don't have compressed air, a hairdryer on the cool setting works for blowing dust out of switches. A small bowl of warm water with two drops of dishwash liquid handles the keycaps. Isopropyl is sold at Dischem and Clicks for around R45 a bottle, a single 200ml bottle lasts for years of cleanings.

Step-by-Step: Quick Surface Clean (10 Minutes)

For weekly maintenance, unplug the board and flip it upside down over a bin, gently tapping the back to dislodge crumbs and dust. Use compressed air in short bursts at a 45-degree angle to push debris out from between the switches, never spray straight down. Wipe the keycaps and switch plate with a microfibre cloth lightly dampened in 70% isopropyl alcohol. Avoid getting liquid into the switches themselves. This routine alone, done weekly, keeps a board feeling new for years. SA dust levels are higher than European or Asian environments, especially in Joburg and the Highveld where dry winter air carries fine particulate, so weekly cleaning is worth the 5 minutes.

Deep Clean: Step-by-Step Walkthrough

For a full deep clean, start by photographing your layout so you remember where the function keys and modifiers go. Unplug the keyboard. Use the keycap puller to pull every keycap straight up, working in rows. Soak all keycaps in a bowl of warm water with two drops of dish soap for 15-20 minutes, then rinse and lay them out on a towel to air-dry, this is critical, residual moisture causes switch corrosion. While caps are drying, flip the board and shake out debris, then use a soft brush to sweep dust off the switch plate. Dampen a cotton bud in isopropyl alcohol and clean around each switch base. For larger keys with stabilisers like spacebar and shift, lift the keycap carefully to avoid bending the wire. Once everything is bone-dry (give it at least 2 hours, longer in winter), reseat the keycaps starting with anchor keys (Esc, Enter, spacebar) before filling in the rest. Total time: about 40 minutes plus drying.

Common Mistakes to Avoid

The biggest mistakes SA users make are using the wrong cleaner and not letting keycaps dry fully. Glass cleaner, all-purpose spray and disinfectant wipes contain ammonia or bleach that fade keycap legends and crack ABS plastic. Stick to isopropyl alcohol or warm soapy water, that's it. Don't dunk the whole keyboard, the PCB and switches are not water-resistant. Don't pry switches off the PCB unless you have a hot-swap board and know what you're doing. And never reassemble while keycaps are still damp, water trapped under the cap will travel into the switch and ruin it within weeks. Avoid coloured rags or paper towels for wiping, they can leave fibres and dye behind on fresh isopropyl-treated surfaces.

Frequently Asked Questions

How often should I clean my mechanical keyboard in SA conditions?

A quick surface clean every two weeks and a full deep clean every three to six months is enough for most users. SA dust levels and dry winter air mean dust accumulates fast, so air-blasting weekly is worth the 30 seconds. Coastal Cape Town and Durban setups deal with salt-air corrosion as an additional consideration, more frequent isopropyl wipes help.

Can I wash keycaps in the dishwasher?

ABS keycaps will warp and lose legends in a dishwasher. PBT keycaps survive a low-heat cycle in a mesh bag, but hand-washing is still safer. The 15-minute soap soak is gentler and just as effective without risking your premium GMK or KAT profile caps.

What if liquid spilled inside my keyboard?

Unplug immediately, flip upside down to drain, remove all keycaps and let it air-dry for 48-72 hours before testing. Sticky liquids like cooldrinks or coffee usually require switch-level cleaning or replacement. If in doubt, take it to your local Evetech service centre for assessment, faster action means better recovery odds.
