Dry red wine stains on a cotton T-shirt can be challenging to remove completely, but with prompt action, you can increase your chances of success. Here's what you can try:
Blot the stain: Start by blotting the stain gently with a clean cloth or paper towel to absorb as much of the wine as possible. Avoid rubbing the stain, as it can push the wine further into the fabric fibers.
Pre-treat the stain: Create a solution of equal parts cold water and white vinegar. Dab the stain with the solution using a clean cloth or sponge. Allow it to sit for a few minutes, then blot with a clean, damp cloth.
Apply a stain remover: If the stain persists, you can try applying a liquid laundry detergent or a stain remover specifically designed for removing tough stains. Follow the instructions on the product and apply it directly to the stained area. Gently rub the fabric together to work the product into the stain.
Launder the shirt: After pre-treating the stain, wash the T-shirt in the washing machine using the hottest water recommended for the fabric. Check the care label of the shirt to ensure you're using the appropriate settings. You can include other clothing items as well, as long as they can be safely washed together.
Inspect the stain: Once the shirt is washed, check to see if the stain has been completely removed before drying it. If the stain is still visible, avoid putting it in the dryer, as the heat can set the stain further. Repeat the pre-treatment and washing process until the stain is gone.
Note that the effectiveness of stain removal can depend on various factors, such as the age of the stain, fabric type, and the specific washing instructions for the shirt. Some older or set-in stains may be more challenging to remove completely.
It's also worth mentioning that it's generally a good idea to wash stained garments separately or with like colors, especially if you're unsure about the stain's complete removal. This prevents the risk of transferring the wine stain to other clothing items during the wash cycle.
