Baby Lock Hydro Melt Water Soluble Stabilizer is the perfect clear topping for projects that use high pile fabrics such as fleece, terry cloth, and knits. It creates a smooth embroidery surface so stitches won't sink into your fabric, giving a crisp definition and detail to your work. Hydro Melt dissolves in water, so it should only be used on projects that can be wet without staining. You can easily remove the stabilizer with a damp cloth or sponge. Do not let Hydro Melt come into direct contact with your iron.
