1. **Degreasing** Black dyeing processing requires complete degreasing due to chemical reactions. (Note: Insufficient degreasing can cause dye unevenness.) For degreasing agents, there is trichloroethylene or a dedicated degreasing agent, the water-based degreasing cleaner Tobikamaritt made by Tobi Corporation. In the case of trichloroethylene degreasing agent, immerse the item to be dyed for 1-2 minutes, ensure sufficient degreasing, then remove and let it air dry. ↓ 2. **Surface Activation** If there is rust or smut, immerse in a 10% hydrochloric acid solution (a solution diluted 2-3 times with water from industrial hydrochloric acid) for 1-2 minutes. ↓ 3. **Black Dye Treatment** Dilute the room temperature black dye Tobik Blackie SN with water (distilled water or tap water) at a ratio of 1:1-2, then place the pre-treated item into this solution, stirring up and down several times, and immerse for 1-2 minutes. (Note: If used undiluted or if the dilution ratio is insufficient, it will result in poor fixation, so be careful.) ↓ 4. **Washing (Hot Washing)** Since black "sludge" adheres to the surface, please wipe it with a sponge or cloth. Additionally, using Chemik's ChemQ Sludge Remover Spray will be even more effective.
