RIT COLORSTAY, 8 fl oz, Dye Fixative (. 0 1 Count - 8 fl oz, Dye Fixative) Product Description Rit ColorStay Dye Fixative reduces bleeding, fading and even enhances the color of your project. It works on cotton, linen, silk, wool, ramie and rayon. For best results, use immediately after dyeing, before rinsing and laundering. Fun tip: Commercially dyed items and previously hand-dyed items can also be treated with ColorStay Dye Fixative before laundering for the first time. However, the results may not be as apparent or long-lasting as when used after your own Rit project. For general projects, use the sink or bucket method. For maximum effectiveness, use the stovetop method. If you are working with small items or are looking to apply ColorStay Dye Fixative to a small / partially dyed (i.e. dip dyed) area, then use the spray method. If you are dyeing large items or are looking for the easiest way to apply ColorStay Dye Fixative, then use the washing machine method.
