Learn how to install and care for double-shot OSA PBT side-printed keycaps, including fit checks, cleaning steps, and profile comparisons.

Quick answer

To care for double-shot OSA PBT side-printed keycaps, remove them with a wire puller, wash in lukewarm water with mild soap, and air-dry fully before reinstalling. Check that each keycap seats flush and that side legends face the front of the keyboard.

Why side-printed legends change your cleaning routine

Side-printed legends sit on the front face of the keycap, so they are less exposed to fingertip oils than top-printed legends. That means you can often clean the top surfaces with a damp cloth without scrubbing near the legends. For deeper cleaning, remove the keycaps and wash them gently—avoid soaking them in alcohol or harsh solvents, which can dull the PBT surface over time.

OSA vs OEM profile: what to expect when swapping

OSA profile is a spherical, sculpted profile that is taller and more rounded than OEM profile. If you are moving from OEM keycaps, the OSA set will feel different—keys are slightly taller and the top surface is more curved. This is a personal preference, not a defect. Also note that OSA keycaps may not fit keyboards with very low-profile cases or tight clearances; check that the keycaps do not rub against the case or stabilizers.

Fit checks before you commit

Before fully installing the set, test-fit a few keycaps on different rows (especially the spacebar and modifier keys) to confirm the stems engage smoothly and the keycaps sit level. If a keycap feels tight, do not force it—lift it and check for obstructions. The supplied set is compatible with many Keychron models, but always verify your specific model against the compatibility list.

Step-by-step care and installation

Remove keycaps safely: Use a wire keycap puller to gently lift each keycap straight up. Common mistake: pulling at an angle can bend stems or scratch the keycap sides. Work slowly and keep the puller vertical.
Pre-clean loose debris: Before washing, turn keycaps upside down and tap out crumbs or dust. A soft brush can help dislodge particles from the underside. Skip this and dirt may turn into mud when wet.
Wash with mild soap and lukewarm water: Fill a bowl with lukewarm water and a few drops of mild dish soap. Submerge keycaps and gently agitate with your fingers. Do not use hot water, alcohol, or abrasive cleaners. Hot water can warp PBT; keep it lukewarm.
Rinse and dry completely: Rinse keycaps under running water and shake off excess. Place them on a towel in a well-ventilated area to air-dry fully—at least a few hours. Common mistake: reinstalling while damp can cause sticky stems or trapped moisture. Ensure stems and interiors are dry before reinstalling.
Reinstall with side legends facing front: Align each keycap so the side-printed legend faces the front edge of the keyboard (toward you). Press down firmly until it seats. Test each key for smooth travel. If a keycap sits crooked, remove and reseat it.
Check for rubbing or interference: After installation, press each key fully and listen for scraping. On some keyboards, tall OSA keycaps may contact the case or stabilizers. If you hear rubbing, try reseating or contact support. Address rubbing early to avoid damage.
