Your ps5 controller need regular cleaning to perform well and last longer. Here's the safe way to do it without damaging sensitive components.
Power off the DualSense controller. Disconnect from the PS5 and any charging cable.
Use a microfiber cloth slightly dampened with isopropyl alcohol to wipe all external surfaces, including the textured back.
Use cotton swabs with isopropyl alcohol around every button, the touchpad edges, the adaptive triggers, and the joystick bases.
Gently brush the speaker grille and microphone opening with a dry soft brush. Use compressed air for trapped particles.
