Removing set-in stains that have been washed and dried can be challenging, but there are a few methods you can try:
- Pre-treat the stain: Use a pre-treatment product or a mixture of equal parts water and white vinegar to pre-treat the stain. Rub the pre-treatment into the stain and let it sit for a few minutes before laundering.
- Use a stain remover: There are many different types of stain removers available, including powder, gel, and spray formulas. Follow the instructions on the product to apply it to the stain and let it sit for the recommended amount of time before laundering.
- Use a laundry booster: Laundry boosters, such as oxygen bleach, can help to remove set-in stains. Follow the instructions on the product to add it to your wash cycle.
- Try a homemade stain remover: Mix equal parts water and liquid dish soap and apply it to the stain. Rub the mixture into the stain and let it sit for a few minutes before laundering.
If the stain persists after trying these methods, you may need to consult with a professional cleaner for additional assistance.
