Ask the Laundress
I had a new pair jeans that I ran through the wash. How do I remove the stains from the red, green and turquoise T-shirts that were affected?
In the future, never wash new jeans, dark colored towels, or any new items with saturated colors with anything else on their first washing.
What you have experienced is dye transfer. Our Stain Solution has removed turquoise dye transfer from Lindsey's white T-shirts. The trick was applying Stain Solution to the dyed areas and soak over night. The next day, rinse the areas, re-apply the Stain Solution and soak.
If you put the shirts in the dryer, you will have to work even harder!

Is it true that soaking my dark jeans in vinegar and water before washing will seal in the dye?
Basically, vinegar is an acid and an acid, such as acid washing, generally does the adverse to color preservation.
Below is information I found about hand dyed yarns and color-fasting them. You will see vinegar is suggested as a fixative, however it states that this doesn't work on cotton which is denim. The most aggressive attempt is to lock in dye would be to use the dharma dye fixative.
Mohair is usually dyed with acid dyes. If a scarf was dyed with acid dyes but was not fixed properly, it might help to heat it in a cooking pot in the presence of an acid, such as vinegar. (Note that this will never work with cotton, but may work with animal fibers such as mohair.) However, you should never use a cooking pot that is intended for food use, because the dye is probably not safe to eat, and tiny amounts of stains might persist to contaminate future uses of the pot. Also, there is no guarantee that the dyer did not use a different dye type, in which case this would not help.
The best suggestion I have for you is to mail-order a commercial dye fixative. Cationic dye fixatives such as Retayne, Raycafix, or Dharma Dye Fixative will fix most dyes, though they do not work on vat dyes such as indigo, nor on basic dyes. You will have to mail-order your Retayne or other brand of this product; most dye retailers online will sell it. These commercial dye fixative products are very useful for fixing the dye in almost any commercial garment that is not washfast, so it is good to have some on hand. Retayne is supposed to be added in hot water, which you may wish to avoid, but Dharma Dye Fixative is supposed to be added to a cold water rinse, which is less worrisome for your mohair. Of course, Dharma Dye Fixative is sold only by Dharma Trading Company, but other dye suppliers may have their own brand names of the same product.
