Rit Color Stay Dye Fixative doubles the amount of colour retention in fabrics dyed with Rit Dye. Works with most fabrics, including cotton, linen, rayon, ramie, jute, and hemp. For best results, use immediately after dyeing, before rinsing and laundering. Can be used when dyeing in the washing machine, sink or stovetop, or can be sprayed directly onto fabric for many craft and DIY applications. 236mL (8 oz) bottle.
