If you accidentally washed white clothes with colored clothes and the colors transferred, causing stains on the white garments, here are some steps you can take to try and remove the color:
Separate the affected clothes: Remove the white clothes from the colored items and keep them separate to prevent further color transfer.
Act quickly: The sooner you address the stains, the better chance you have of removing them successfully.
Assess the fabric and color: Check the care labels on the white garments to determine if they are colorfast and can withstand certain treatments. If the items are delicate or made of sensitive fabrics, consider taking them to a professional cleaner.
Pre-soak in cold water: Fill a sink or a large basin with cold water and soak the stained white clothes for about 30 minutes. Change the water if it becomes discolored.
Spot treat with detergent or stain remover: After soaking, apply a small amount of liquid laundry detergent or a stain remover directly to the stains. Gently rub the fabric together to work the detergent into the fibers.
Use oxygen bleach: For white fabrics that can tolerate it, you can use oxygen bleach to help remove the stains. Follow the instructions on the product's packaging for the appropriate dilution and soaking time.
Launder separately: Once you've treated the stains, launder the white clothes separately from colored items. Use the hottest water suitable for the fabric and a regular laundry detergent. This should help to further lift the remaining stains.
Check before drying: Before drying the clothes, check to see if the stains are completely removed. If any stains persist, avoid drying the items as the heat can set the stains, making them more challenging to remove later.
Sun drying: If the stains persist after washing, hang the white clothes in direct sunlight. The sun's natural bleaching properties can sometimes help to lighten stains. However, be cautious with delicate fabrics, as prolonged sun exposure may cause damage.
Repeat if necessary: If the stains are not entirely removed after the first attempt, repeat the treatment process until you achieve satisfactory results.
Remember, removing color stains from white clothes can be challenging, and success depends on various factors, including the fabric type, the type of colorant used, and the time that has passed since the staining occurred. If you're dealing with valuable or delicate items, it's best to seek the advice of a professional cleaner.
