I'd like to get your views on repairing colour run.
A customer bought me a red Persian rug for cleaning. It was clear that the red had run into the cream border on a previous wash. I found that I could clean ok using fineline and then an immediate extraction with an acid rinse, working on small areas at a time. The rug looks well, but removing the muck has made the colour run show up much more. I'd like to try to repair this if I can and I'd like some suggestion the best technique
