To clean dirty white shoes effectively:

1. Remove loose dirt using a dry soft brush or toothbrush.
2. Make a mild cleaning solution using warm water and mild detergent or dish soap.
3. Remove and hand wash shoelaces separately with the cleaning solution.
4. Clean the soles thoroughly with the brush and cleaning solution.
5. For the uppers, gently scrub with the cleaning solution using a soft brush or cloth, then blot with a dry cloth to lift dirt and moisture.
6. Allow shoes to air dry at room temperature completely.

Additional effective cleansers include a paste made from equal parts baking soda and water, white vinegar mixed with water, or plain white toothpaste applied with a toothbrush. For stubborn stains, apply a baking soda and hydrogen peroxide paste, scrub, then let dry in sunlight before brushing off. Magic erasers work well on tough outsole stains. Avoid machine washing or using high concentrations of soap, which can damage materials or cause discoloration. These methods work well on canvas, leather, and rubber parts of shoes, helping restore white shoes close to like-new condition.
