What is the best way to remove yellow highlighter stains from cotton cloth?

Soaking cotton in an oxygen bleach solution removes the stain without damaging the fabric, according to the StainSolver Corporation. It recommends mixing 4 to 6 ounces of oxygen bleach in 1 to 2 gallons of warm water and soaking in a bucket until the stain is no longer visible.

One should immerse the entire garment in the solution as quickly as possible after finding the stain. Once the stain is gone, one should remove the article from the bucket and machine wash normally.

On cotton upholstery, the recommended procedure is wetting the fabric with a dilute oxygen bleach solution and allowing it to sit for 15 minutes. At the end of the time period, one should soak excess solution from the upholstery using an old towel, repeating the entire process as necessary to eliminate the stain.
