Fabric conditioner for washing machine softens fabrics, reduces static cling, and leaves clothes smelling fresh. It is used in the final rinse cycle of the washing machine, and it works by coating the fibers of the fabric with a thin layer of chemicals. These chemicals help to lubricate the fibers, which makes them feel softer and less likely to cling to each other. Fabric conditioner also contains fragrances that help to leave clothes smelling fresh.
