So, I just bought a 4 channel true bypass looper thing. You know the deal.

When I first started using it, it worked great, switches were quiet, everything was great. Then I rearranged my pedals and now all the switches have this scratchy fuzz sound when I step on them.

I always go to contact cleaner - DeOxit - for scratchy switches. I'm not too familiar with exactly which switch you're talking about though. . . .
