My husband's yellow ren shirt has faded, so I bought some Rit dye. I know people have said that you set the color of a dyed item by using vinegar, but I haven't figured out how to do it.
Is it plain white vinegar? Do you put it in the water with the dye & the shirt, or do you rinse the shirt and then put it in the vinegar? Mixed with water? Hot water, cold water, tepid?
I really need instruction on dyeing for dummies. If someone can tell me the process step by step, I would really appreciate it. Thank you.
For RIT, I use salt in the washing machine with the dye. It works well!
For any dyes, I use salt and calsolene oil which I get from Dharma trading. But for a relatively lihgt color like yellow, just salt should be sufficient. I use white vinegar to remove stains on fabric that can't be bleached.
