Remove fruit stains

Fruit stains, especially the dark, are very feared, because they go out badly when washing. I have had good experiences with the following tips:
Treat fruit stains with vinegar or lemon juice before washing. The acid crackles the tannic acid in the fruit stain and the stain goes out better when washing.

Red and dark fruit stains e.g. of cherries or elderberries can be treated well with plain water. Place the laundry with the stains as quickly as possible in cold water and leave it in the water for a while. Mostly the stain dissolves in the water. If he is not out yet, continue as described above. The pretreatment with water is m.E. better than the immediate treatment with acid.
