A common misconception about red wine stains.
Three out of four people will tell you that you should put salt on a red wine stain, or worse, they will rush to the salt shaker before you have time to say "phew" and in a heroic gesture they will fix for good this poor stain that had asked nothing of anyone.
If you are dyeing fabric, you will use coarse salt to fix the dye, if you are painting on silk you will do the same. Salt is a fixative and in contact with the tannin contained in the red wine it will redouble its effectiveness by an oxidation effect.
The solution is so simple.
We didn't invent anything, our grandmothers knew it. Just soak it, and rub the stain with ox gall stain remover soap, the stain won't resist it.
To use as a pre-wash:
Wet the fabric with lukewarm water, soak the stain with the gall soap, lather and leave to act. After a few minutes or a few hours depending on the nature of the fabric and the stain, machine wash the laundry on the usual program. In the case of stubborn stains such as Indian ink, it is sometimes necessary to soak the stain several times before washing. If a red wine stain has been salted, you can still remove it using Bionatura stain remover soap with ox gall, but you will have to insist and leave it to act longer before machine washing.
For other stains, lipstick, sauce, pollen, grease, oil, dirt, grass, carrots, proceed in the same way.
For blood stains , wet the fabric with cold water and proceed in the same way.
I managed to remove a stain of Indian ink from a pair of white trousers perfectly. I couldn't believe it myself. For three days, morning and evening, I wet it with warm water and soaked it heavily with gall soap. On the fourth morning, the result was obtained.
