I knit some really cute LTK shorties for my son, in Cascade 220. I used green and white and made wide stripes. When I lanolized them, the lanolin "stained" the white stripes (it's not really stained, I guess, there are just spots of lanolin that you can see on the white). I tried running hot water right on the spots, to melt it and rinse it off, but they didn't budge. Any suggestions?
