Sewing machine oil is a specially formulated lubricant designed to keep sewing machines running smoothly. It reduces friction between moving parts, preventing wear and tear, and helps maintain the machine's performance over time. Using the right oil is essential, as it ensures that the machine operates efficiently and extends its lifespan. Typically, sewing machine oil is lightweight and clear, making it suitable for delicate components. It is important to apply the oil sparingly and only in designated areas, as excessive oil can attract dust and lint, leading to potential issues. Regular maintenance with sewing machine oil is key to optimal functionality.
