Two types of dyes are used in Octopus inkjet inks: Water-soluble and pigment dyes. Water-soluble ones, as the name implies, are completely dissolved in water and can therefore penetrate far into the textile fiber with the water from the ink. Pigment dyes generally only attach themselves externally to the fibers. However, both dyes can adhere to the fibers via molecular interactions up to chemical bonding. This depends on the chemical properties of the dye. Removing a dye from hands or textile fibers purely mechanically is therefore very difficult. Furthermore, when removing stains, haste is required, otherwise the dyes will penetrate too deeply to be removed again.
How to remove ink stains from hands, clothing or fabric?
Note: Rinse the stained textiles or hands immediately with cold water. Then proceed as described below in each case.
Ink stains on hands
Wash your hands with hand washing paste to mechanically rub the ink off your hands. Then wash your hands with soap. Finally, rub your hands with a moisturizing hand cream. For stubborn cases, use a washing paste with chemical additives that destroy the dyes reductively, e.g. ReDuRan (Octopus Art. No. RED250).
Ink stains on white textiles
If splashes of colored inkjet ink have gotten onto white textiles, use chlorine bleach and cold water to remove the stain. You must act quickly here, however, or the ink will penetrate too deeply.
Please do not use warm or hot water! This will only bind the dye more tightly to the fiber.
Ink stains on colored textiles
Use a mixture of detergent and ammonia solution diluted with cold water. Again, you must act quickly. Furthermore, you should test on an inconspicuous spot whether the cleaning solution attacks the color of the fabric. Please do not use warm or hot water.
Warning: Never mix ammonia water with chlorine bleach. This produces toxic fumes!
