Club soda, diswashing liquid and vinegar for red wine stains
If the wine stains are fresh, you can saturate them with club soda, then wash. Or, you can apply a mixture of dishwashing liquid and vinegar. This is safe on all washable fabrics. Or, if your garment is shrinkproof, place it in a pot containing enough milk to cover the stain, bring to a boil, remove from heat, and let sit until the stain has disappeared.
