Red wine can leave stubborn stains on leather products that can only be removed if you act quickly. The longer the stain is on the skin, the more difficult it will be to remove. When dealing with other materials, it is advisable to first make sure that the stain remover you use will not affect the color or finish of your clothing or furniture. In the case of leather, however, time is of the essence, and the only chance to remove the stain is to immediately treat it with the least corrosive substance at your disposal.
Steps
If you do not have a commercially available stain remover on hand, do the following immediately.

Step 1. Sprinkle plenty of table salt over the stain
The salt absorbs the red coloring matter and prevents the stain from sticking to the skin.

Step 2. Leave the salt for a few minutes to absorb liquid and coloring matter

Step 3. Gently sweep the remaining salt from the skin
Use a soft art brush or baking brush if possible.

Step 4. Blot with a lint-free, undyed cloth to remove excess moisture
Do not rub the fabric; just blot.

Step 5. Dampen the stain with white wine

Step 6. Blot again and dry
If the stain still hasn't come off, apply soda water.

Step 7. Dry again by blotting lightly with a lint-free cloth

Step 8. Air dry the leather product or use a hair dryer at low power

Step 9. When the leather is dry, treat it with leather conditioner or saddle soap
This is important as dry skin cracks easily and can take on a worn look. A leather conditioner adds moisture to the skin.
Advice
- Start removing the stain as soon as possible.
- Take action quickly but carefully.
- Use cold whole milk if you don't have white wine or soda water on hand. Like salt, milk will penetrate the skin and absorb red wine.
- Treat red wine stains on your skin with non-bleaching liquids: white wine, soda water, milk, or cold water. Never use an acidic liquid such as lemon juice.
- Don't rub too hard, even if the leather is strong. Friction will spread the stain and damage the skin.
Warnings
- Only dry cleaning is suitable for leather products, so use leather products with caution.
- Use commercially available leather stain removers with caution, some contain flammable chemicals.
