Message: Hello, I am concerned because I have bleach spots on my Terry material pants and they are black. Exactly what type of dye to use, the material says 80% cotton and 20% polyester. Would I have to dye the entire pants or is there a way that I can only dye the bleach spots. Please help me!!! Thank you!!!

Here's the page you need to read:

How can I fix bleach spots on clothing?
If you dye the pants, only the 80% of the fiber that is cotton will take the color. This means that you will only be able to produce a dark gray, not a black to match the rest of the fabric. Using a marker, as described on that page, is the best thing to try, though the results will not be perfect.
