Now that I have made the switch from Kool-aid to Lanaset, does anyone have any tips for clean up. I'm waiting for my roving to dye and I'm seeing purple drips in my tub. I think I may need a bit more than bleach, since I already washed and rinsed the fiber. I'm guessing it may not be as machine washer friendly as most of the yarn I've spun. Any tips would be appreciated.
