[Dye Stain Removal on the spotting board]

  1. Prepare dye stripping solution: Water 95%, YellowGo (titanium sulfate) 3% and RustGo (rust remover, acid) 2%. Add enough RustGo to change black solution to light green.
  2. Apply the solution directly on the dye stain.
  3. On white garments, heat with steam
  4. On colored garments, test if the base color goes away with the dye stain.
  5. If the base color fades, neutralize with ammonia or alkali. In most cases, the base color will return.
  6. Flush and finish

[Dye Stain Removal – bath method]

  1. Prepare dye stripping solution in a bucket: Water 95%, YellowGo (titanium sulfate) 3% and RustGo (rust remover, acid) 2%. Add enough RustGo to change black solution to light green.
  2. Water temperature: 27℃ (80℉) ~ 65℃ (150℉). The hotter the water, the stronger the stripping action
  3. With white garments, you can go as hot as you want. The solution can be more concentrated as well.
  4. On colored garments, use lower temperature and shorter soaking time. Check frequently if the base color fades.
  5. If the base color fades, neutralize with ammonia or alkali solution. In most cases, the base color will return. Thicker fabrics require longer neutralizing time.
  6. Flush and finish

[Dy Stain Removal – washer method]

  1. After you fill the washer, add YellowGo (titanium sulfate) and RustGo (rust remover, acid). Add enough RustGo to change black color to light green.
  2. Water temperature: 27℃ (80℉) ~ 65℃ (150℉). The hotter the water, the stronger the stripping action
  3. With white garments, you can go as hot as you want. The solution can be more concentrated as well.
  4. On colored garments, use lower temperature and shorter soaking time. Check frequently if the base color fades.
  5. If the base color fades, neutralize with alkaline soap. In most cases, the base color will return. Thicker fabrics require longer neutralizing time.
  6. Rinse and extract.
