How do I bleach shoestrings?
To whiten shoelaces like the cotton ones on athletic shoes and sneakers, you can try soaking them in a solution of ¼ cup Clorox® Disinfecting Bleach added to 1 gallon of water. Start by putting the shoelaces in a lingerie bag. This will prevent them from getting tangled when they are machine washed following the bleach soak. Then, fully submerge the shoelaces in the bleach solution for five minutes, weighing them down with a dishwasher safe plate if the lingerie bag tries to float. After 5 minutes, drain the soaking solution, and wash the shoe laces (still in the bag) in hot water using detergent and ⅓ cup Clorox® Disinfecting Bleach. Let the shoe laces air dry. How well they turn out depends a lot on how long they have been worn without being washed. The longer a stain sits, the harder it becomes to get out completely.
