I'm more than a little embarrassed about how much debris was sitting in my serger when I finally cleaned it today. BUT, I decided to use it as an opportunity to share my best tips for how to clean your serger!
Ok, yeah, I know I'm guilty here. But seriously - fuzz, debris, thread, etc sitting inside your serger is a disaster waiting to happen. Don't ignore it, it's really bad for your machine!
A lot of people blow out their machines with canned air, but this is actually quite risky - it can put moisture inside your machine and create rust, and it can also blow the debris further into your machine.
Professionals who do machine maintenance usually use a compressor to blow air, and they take the machine completely apart before blowing it out.
If you have access to a small vacuum, this is a great way to suck up the larger debris. I got a mini battery operated vacuum off of Amazon, which I use first to remove as much as I can with it.
A large artist's paintbrush (or cheap kids version) is the perfect tool for cleaning a serger - as you run it over the part sand into the corners, the fuzz naturally sticks to it, and you can then dispose of it in the garbage.
A small artist's paintbrush (or again the cheap kids version) works best for cleaning the remaining crevices that were too small to get your large brush into.
