Getting White Washclothes White AgainMy white washcloths turn pinkish after continual uses and washes. I tried using bleach to get the hint of pink out, but that doesn't work. I'm guessing that this pink occurs from the type of water we have. I notice that my toilet bowls turn pinkish when they are not cleaned within 10 days. After scrubbing the toilet bowl, though, the pink tint does go away. But this isn't the case with the washcloths. Any ideas on reasons and solutions out there? I only wash the washcloths with whites--no dark colors, etc. Thanks!
