Rit ColorStay Dye Fixative 3-Pack — Fabric Colour Retention for Cotton, Linen & Rayon

Rit ColorStay Dye Fixative is a post-dye treatment that locks colour into natural-fibre fabrics to reduce bleeding and fading and keep dyed projects vibrant longer.

If you spend time dyeing clothing, home textiles or craft pieces, the final step matters. Rit ColorStay is formulated to set dye after the colouring process so pigments stay where you put them instead of migrating or washing out. It's a convenient, rinse-and-go solution designed for use on cotton, linen, rayon, ramie and blends containing those fibres, and it works on both home-dyed and commercially dyed items.

How does Rit ColorStay help my tie-dye and dip-dye projects?

Use ColorStay right after you remove excess dye to prevent colours from running into adjacent white or light areas. It stabilises the dye on fibres so patterns stay crisp and colour transitions remain clear.

• Apply after rinsing or before the first wash to minimize bleeding.
• Ideal for multi-colour tie-dye to preserve defined lines.
• Helps keep bright hues from dulling during laundering.

What fabrics does this fixative work best on?

ColorStay performs best on natural and semi‑natural fibres that readily accept dye. Fabrics with a high proportion of cotton, linen, rayon or ramie will see the most benefit; blended fabrics containing these fibres also respond well.

• Great for 100% cotton shirts and linens.
• Effective on rayon and ramie garments and trims.
• Works on blends that include the above fibres—test first on mixed synthetics.

How do I use Rit ColorStay for reliable results?

The application is straightforward: after dyeing and rinsing, treat the fabric according to package directions to set the colour. Follow temperature and timing guidance on the label for best stability, and launder as recommended once the fixative has done its work.

• Use immediately after dyeing or rinsing tie-dye pieces to prevent colour migration.
• Follow label instructions for solution concentration and soak time.
• Rinse and wash per care directions after treatment to remove excess fixative.

Will ColorStay work on commercially dyed garments?

Yes—this fixative can improve colour retention on factory-dyed textiles by reducing dye loss during washing. Results depend on the original dye method and fabric content, so perform a small test on hidden seams if the garment is valuable.

• Helpful for refreshing colorfastness of store-bought items.
• May not fully restore poorly dyed items but can reduce additional fading.
• Always patch-test delicate or expensive pieces first.

Who is this for: crafters, small-batch clothing makers, DIY decorators and anyone who wants dyed fabrics to look as bright after laundering as they did right after dyeing. If you work with cotton, linen, rayon, ramie or blends and need cleaner pattern edges and longer-lasting colour, Rit ColorStay Dye Fixative 3-Pack gives you multiple treatments to protect several projects or to keep on hand for repeat use.
