Use a small brush or toothpick to gently dislodge any lint or threads stuck in the needle plate or bobbin area. Go slowly and be patient – removing stuck threads takes time and care. Tweezers can help grasp and pull out any stubborn threads.
You can also use a can of compressed air to blow away dust and debris. With some effort and patience, you’ll have that area cleaned up in no time.
Try cleaning in sections, focusing on one area at a time. Use a bright light and magnifying glass to see the threads better. Take breaks to rest your eyes. For really stubborn threads, a seam ripper may help slice under them to loosen their grip.
Avoid metal tools around the needle plate which could scratch the surface. Work methodically and carefully. Proper lighting, magnification, and tools are key for this tedious but satisfying sewing machine cleaning task.
