The spot remover removed not only the butter spatters but also the dye (see previous post), so I thought I'd finish the job, this time with an intentional dye discharge since the shirt wasn't fit to wear in its current condition. My first attempt involved using the same spot remover that had removed the butter and the dye. I gathered the shirt in pleats and put rubber bands on it and put the spot remover on. After two attempts, no additional dye had been discharged. So, I rinsed the shirt, mixed up a thiox solution and applied it. Again, no luck. Odd, it always worked before. I thought maybe I'd mixed it incorrectly, so I made ANOTHER thiox solution and applied it and, you guessed it, no luck! The shirt was ruined anyway, so in desperation, I rinsed the shirt again, pulled out the chlorine bleach, applied it to the shirt and TA-DA! The color disappeared in a wink. I had some anti-chlorine drops on hand, so I soaked it in a solution, so the shirt should be okay.
