Rit ColorStay Dye Fixative is the key to long-lasting, vibrant color. Designed to lock in color after dyeing, it keeps fabrics looking their best and brightest. This fixative reduces bleeding and fading, while even enhancing the color of projects. Best on cotton, linen, rayon, or ramie, it's also effective on commercially dyed fabrics. Whether used after dyeing or immediately after tie-dye, expect lasting color.
