To clean guitar pedals with contact cleaner, you typically spray a small amount into the jacks, potentiometers (pots), and switches to remove dirt, dust, and oxidation that can cause crackling or signal loss.
Deep Cleaning Your Guitar Pedal
Over time, grime can build up on the connectors and internal components of your guitar pedals, affecting their performance. Contact cleaner is a specialized spray designed to clean these electronic parts without damaging them (ensure you use an electronic-safe version).
Here's a step-by-step guide on how to use it effectively:
-
Safety First:
- Unplug your pedal completely from the power supply and your guitar/amp cables.
- Place the pedal on a clean, stable surface.
-
Prepare the Pedal:
- If possible and necessary for cleaning around the base of the pots or switches, you might consider gently pulling off any knobs. Take care not to damage the shafts.
- For thorough cleaning or to access internal points, you may need to open the pedal. As shown in the reference clip (YouTube: 2:29 - 3:35), this often involves unscrewing the backplate to check inside and wipe the bottom plate. Opening the pedal allows better access to the solder points of jacks, pots, and switches if needed.
-
Apply Contact Cleaner:
- Jacks (Input/Output): Insert the nozzle of the contact cleaner spray into the jacks and give a very short burst. This helps clean the internal contacts where your cables connect. You can then insert and remove a clean guitar cable a few times to help wipe the contacts.
- Potentiometers (Pots): Locate the base of the potentiometers on the circuit board (this is often easier if you open the pedal). Apply a tiny amount of cleaner where the shaft meets the housing, or into any small openings on the pot body. Crucially, rotate the knob through its full range of motion several times. This action helps the cleaner work the debris out.
- Switches (Footswitch, Toggle Switches): For toggle switches, spray a tiny amount into the switch mechanism, often accessible from the outside or after opening the pedal. For the main footswitch, applying cleaner is trickier and often involves accessing its base on the circuit board if the switch type allows for cleaning. Actuate the switch several times after applying cleaner.
-
Let it Dry: Contact cleaner is usually fast-drying, but it's important to let it fully evaporate before powering the pedal back on. This typically only takes a few minutes in a well-ventilated area.
-
Reassemble:
- If you opened the pedal, carefully put the backplate back on and secure the screws. Remember the clip shows wiping the bottom plate when the pedal is open – this is a good practice for general cleanliness while you have it open.
- Replace any knobs you removed.
-
Test: Plug your pedal back in and test all the jacks, pots, and switches to ensure smooth, noise-free operation.
Choosing the Right Cleaner
- Always use a contact cleaner specifically designed for electronics.
- Avoid cleaners that leave a residue or lubricant unless specifically intended for lubricating pots (which is a different process). A good contact cleaner evaporates completely.
- Look for cleaners that state they are safe for plastics.
Important Considerations
- Use contact cleaner sparingly – a little goes a long way. Excessive spray can potentially damage components or the pedal's finish.
- Ensure good ventilation when using spray cleaners.
By following these steps, including opening the pedal to access components and wipe surfaces like the bottom plate as part of a thorough cleaning process, you can effectively use contact cleaner to restore functionality to noisy jacks, scratchy pots, or intermittent switches on your guitar pedals.
