My "silk flowers" used in outdoor planter baskets are leaking red dye down my wall. How do I remove the dye from the silk flowers off of the baskets and wooden walls on the outdoor surface of my house?
I certainly haven't had any experience with this, so if I were you, I would start off with just some Dawn in water, and see if that takes it off. It may not be that difficult since it just dissolved in water. If that doesn't work, I would try bleach, which is great for taking colors out of clothes! Good luck!
