I have 2 wool covers that I just started using. One of them is dyed, and the dye bled onto one of DD's diapers. Do I need to do anything special to get the dye out of the diaper, or will it just wash out? Also, is there anything I can do to set the dye better so that this doesn't happen again? Also, the other wool cover is natural colored, and it got a little dirt on it when she was playing outside. Will the dirt just come out when I wash the cover, or should I try to scrub it out? Would I use a toothbrush, or something else? TIA!
