Ink can be removed from silk Shantung fabric by a process involving white vinegar, hair spray, rubbing alcohol and water. A home remedy for washable silk suggests using vinegar and milk to remove blue ink stains.
Removing blue ink from silk fabric starts with sponging the stain lightly with water. The ink should then be sprayed lightly with hair spray to loosen it. Next, it should be spotted with a solution combining one part glycerine and one part dishwashing detergent with eight parts water. Then, a few drops of white vinegar should be placed on the stain. The next step is to let the stain rest for 30 minutes, blotting it every five minutes and adding more spotting solution and white vinegar if needed to keep it damp. The silk should then be flushed with water to wash away the solutions. If the stain is still present, rubbing alcohol should be applied to the stain, blotting every few minutes.
