My toddler came home yesterday from daycare and had these brown stains all over her hands. We have tried soap and water, salt with vinegar/lemon juice, hydrogen peroxide, toothpaste with baking soda, peroxide, baby oil, isopropyl alcohol, etc. I don’t know what else to do. It makes her look like we don’t give her baths but this stuff is not coming off. I asked the daycare about it and they checked and said the only thing they could think of was the rust from the toys outside. But rust shouldn’t be this hard to get off. Anyone else been through this? I’m so aggravated with her daycare right now.
