The most effective way to remove a stain from your shirt is by using a stain remover or detergent. Make sure you read the instructions on the product before use and follow them carefully. You can also try pre-treating the stain with a mix of equal parts water and rubbing alcohol, then wash as usual. If the stain persists, consult a professional cleaner for advice.
