Color transfer from one garment to another during laundering, often called dye bleeding or color running, occurs when unstable dyes leach out of fabric, particularly in the presence of water and detergent. This can result in unwanted discoloration, especially on lighter-colored items. For example, a red sock washed with a white shirt might leave the shirt tinged pink.
Preventing and addressing this issue is crucial for maintaining the appearance and longevity of clothing. Restoring stained garments saves money and resources compared to replacing them. Historically, various methods, from natural remedies like vinegar soaks to specialized commercial products, have been employed to counteract dye bleeding. This underscores the enduring challenge presented by unstable dyes and the ongoing need for effective solutions.
