I regularly clean the bobbin area, but haven't opened the bottom plate before. This is what I found, Yikes!!! Look at all the lint that has accumulated over the years!
The inner works is full of little grey rabbits! It really needs a good spa treatment, and I can do a lot myself.
I used the sewing machine brush and got it all out. Now the sewing machine should have a much better performance than before.
This is a treatment that most of you can do yourself, there is a lot of lint accumulating in your sewing machine over time.
I will definitely do this regularly, once or twice a year should be appropriate, in addition to a good bobbin clean out after each project is completed.
Keep on quilting!
