I have used this for years. It must be Dawn BLUE. The other colors do not seem to work.
DH spilled sosme red wine on a white sweat shirt last night. This morning I used this and put it in the laundry. The stain came right out. I also used it on a "mystery" stain on my shirt. It also came right out. This will definetly be in my laundry room. It works and it's cheap.
