Common mistakes to avoid

❌ Do not spray from the outside through the shaft. This washes away the damping grease inside the potentiometer, removing the smooth turning feel and potentially shortening its lifespan.

❌ Avoid universal sprays or WD-40-type products – they leave residues and can damage the carbon tracks.

❌ Never force a stiff knob – it can break the shaft or the internal wiper.

Safe cleaning recommendations

• Access the potentiometer from inside the unit by opening the device and reaching the housing directly.
• Use contact cleaners designed for audio electronics (e.g., DeoxIT Fader, Kontakt 60 + WL, or similar).
• Apply sparingly – a small amount is enough. Avoid flooding the component.
• Rotate the knob gently several times after applying to distribute the cleaner evenly.
• If the issue persists, the potentiometer may require professional servicing or replacement.

Preventive tips

• Keep your gear covered when not in use to minimize dust.
• Maintain stable environmental conditions to avoid oxidation.
• Schedule periodic servicing if you use your equipment intensively (clubs, studios, live shows).

✨ Proper cleaning restores sound quality while preserving the smooth feel and extending the life of your potentiometers.
