Why Do White Sneakers Turn Yellow? Causes and Prevention
White sneakers can turn yellow because of oxidation, material aging, cleaning-product residue, environmental exposure or changes in rubber, foam and adhesives. Yellowing is not always caused by dirt, so ordinary cleaning may not reverse it. To reduce the risk, clean sneakers with material-appropriate products, remove residue carefully, dry them away from excessive heat and store them in a clean, dry place away from prolonged direct sunlight.
