deColourant - Colour remover paste - Jacquard Discharge Paste | 946ml
Available, delivery time: 1-3 days
Jacquard deColourant Paste: paint colour away instead of adding it
A light pattern on dark fabric, stars on midnight-blue velvet, lettering that glows out of a black T-shirt.
With fabric paint that is hardly possible. With Jacquard deColourant Paste it is.
You paint, stamp or print the paste on, iron it, and in those places the colour disappears from the fabric.
Unlike bleach, deColourant does not attack the fibre. The fabric becomes neither brittle nor thin.
For costume designers a wonderful tool for distressing, designing and reworking.
At a glance
• Colour remover paste, 236 ml or 946 ml
• Removes colour precisely from dyed natural fibres and paper
• No bleach, the fibre stays intact
• For painting, stamping and screen printing
• Activated by heat, even stronger with steam
• Also available as a spray mist: deColourant Mist
Ideal for distressing
Selectively lightened knees, elbows, hems and edges make a costume look worn and lived in. With the paste you place these areas exactly where they belong.
What does deColourant remove colour from?
deColourant removes colour from dyed natural fibres such as cotton, linen, viscose and silk, as well as from craft paper. It works particularly well on fabrics dyed with fibre-reactive dyes such as Procion MX . The result is not always white: some dyes leave a light shade, some can hardly be removed. So always test on an inconspicuous area first.
And then?
You can redesign the decoloured areas with Dye-Na-Flow or other fabric paints. This creates light motifs on a dark background that would not be possible with fabric paint alone.

Jacquard deColourant Paste: Instructions
Work in a well-ventilated room, wear gloves and avoid prolonged skin contact. Always test on an inconspicuous area first.
1. Pre-wash the fabric so that deColourant can soak in evenly.
2. Paint, stamp or print the paste onto the dry fabric.
3. Let deColourant dry completely.
4. Iron the areas at the highest setting suitable for the fabric. With steam, the colour is removed even more strongly. Alternatively, you can use a heat press or heat gun.
5. Repeat the ironing until the desired effect is achieved.
6. Then wash the fabric with Synthrapol or a mild detergent so that it becomes soft again.
In case of eye contact, rinse immediately with water. In case of skin contact, wash thoroughly with soap and water. Keep out of the reach of children.
Good luck!
Jacquard deColourant: Frequently asked questions
FAQs Jacquard deColourant & deColourant Mist
deColourant is a non-bleaching colour remover. After it is applied to the dyed fabric, it is activated by heat, either with an iron, a heat press or a heat gun. After the colour has been removed, the deColourant is washed out.
Why use deColourant instead of bleach?
Bleach is an aggressive chemical that can weaken and damage the integrity of a fibre. deColourant only acts on the dye used to colour the fabric and leaves the fibre intact. Bleach can also be harmful to health. Please also observe the hazard information in the description for deColourant.
Is the name deColourant from another brand?
deColourant was the name of a product made by Harbor Sales. Harbor Sales' deColourant was very similar to Jacquard's Discharge Paste. Jacquard has offered Discharge Paste for a long time, and over the years many of our customers have said that they love the product but find the name “Discharge Paste” unpleasant. “Discharge” is the technical term for removing colour from dyed fabrics, but we know it has a negative connotation outside the world of textiles. When Harbor Sales asked whether Jacquard was interested in taking over the deColourant name and product line, we seized the opportunity.
Does Jacquard's deColourant differ from the original Harbor Sales deColourant product?
The only difference is that Jacquard's product is not scented with citrus fruits, as Harbor Sales' was.
Does the new branded deColourant product differ from the former Jacquard product Discharge Paste?
The only difference is that the new deColourant product is significantly stronger than the original Discharge Paste (and therefore tends to work better!). The flow properties are also somewhat different, but if anything, they have improved.
Does Jacquard deColourant Mist differ from the original Harbor Sales product?
The only difference is that Jacquard's product is not scented with citrus fruits, as Harbor Sales' was.
What happened to the other deColourant products from Harbor Sales?
Harbor Sales used to offer deColourant, deColourant Mist, deColourant Plus (a colour paste) and deColourant SP (for screen printing). The last two products have been discontinued and are no longer available. However, deColourant Plus is easy to reproduce by mixing deColourant or deColourant Mist with one of the Jacquard paints such as Dye-Na-Flow or Textile Color. Jacquard's deColourant is also excellent for screen printing.
I tried deColourant on a natural fabric that I did not dye myself, and it did not work. Why not?
Not all dyes can be discharged. Some can be discharged down to white, while others cannot be discharged at all. That is why we always recommend testing the fabric first if possible. You never know what ready-made textiles and garments were dyed with. If you want consistent results, dye the fabric yourself with a dye that you know can be discharged (we can recommend some!), or use a brand that you trust to be consistent.
Does deColourant only work on fabrics?
deColourant can be used on any dyed natural surface. (Again, not all dyes can be discharged.) It works well on most craft papers, for example. It does not work on pigmented paper or painted surfaces.
Do deColourant and deColourant Mist have to dry before heating?
Moisture must be present when heating to activate the chemical reaction. Heating therefore works better when the print is still damp. As the print dries, it becomes more and more important to use steam when ironing.
Do I have to wash my fabric immediately after heating? How long can I wait?
Once the print has been heated and the colour has been satisfactorily removed from the fabric, there is no rush to remove the deColourant.
Can I add colour to deColourant? Which products work well for colouring deColourant?
Adding paints and inks to deColourant is a great way to work additively and subtractively at the same time! If you mix deColourant with a transparent paint such as Jacquard's Dye-Na-Flow, you get incredibly vibrant colours on black fabric, which is always a challenge for textile artists. Try combining deColourant with Neopaque, Textile Color, Airbrush Color, Dye-Na-Flow, screen printing inks or other water-based paints.
What is the ideal heat/temperature for decolouring my fabric?
Use the highest temperature setting suitable for the type of fabric. Using steam also makes the reaction easier.
What do I do if I spill deColourant or it gets onto an area where I do not want it?
deColourant is easily removed with water and is only activated by heating. So if you get some on an unwanted area of the fabric, simply wash it out!
