A Clean sewing machine is a Happy sew machine. Use Quilt in a Day's cleaning brushes to help keep your sewing machine clean and clear. Your machine should be cleaned after every project to keep it running in optimal condition and it is better to pull lint and dust out than blown in. These little Brushes are ideal for just that! They are small enough to reach and grab lint balls that collect in the areas under the needle plate of your sewing machine and the bobbin case.
