Anyone know a good way to clean out the contacts in pedals? I've been using contact cleaner and a 9mm wire brush to clean the contacts. But its starting to fail at cleaning it.

Not sure if this goes here, its not customizing, just cleaning.
The in/out jacks?

If they're getting nasty and contact cleaner's not helping, time to replace them.

Easy and cheap job.

Not all contact cleaner is created equal, though, try de-oxit.
